Horrid. As a Elite/Platinum flier on other U.S. carriers, I can honestly say that Frontier is the worst airline I've ever flown. Other airlines have their challenges, but Frontier sets itself apart. At the bottom.

Our first flight on Frontier was our whole family: two adults with two children 4 and under. No preboard opportunity, cranky gate agents and flight attendants, but we at least sat together. On the return, our family was scattered throughout the plane because we didn't get seats together when they assigned them at the gate. The gate agent told us we were out of luck for assignments and that it was up to us to negotiate with the other passengers to rearrage their seats so that my wife could sit next to our infant daughter. No attempt at customer service, no explanation, just a not-too-polite "deal with it yourselves" from their gate agent. OK, that was bad enough...

Fast forward two years: We're going to visit relatives in CO, and I'm shopping for fares. Frontier was a bad experience the first time, but their tickets are cheap. I can deal with some BS if the price is right. But this time I discover: You can't buy an economy ticket and select your seat. I can buy the cheap seat, but I have to wait until check in to get my seat. I'm still going to be travelling with two small children (ages 2 and 5) and I have to rely on the luck of the draw to hope to sit together, or perhaps on the charity and cooperation of the gate agent? That's pretty unlikely given our past experience. Sitting with my family on a plane is not something I want to leave to chance or the moods of a gate agent.

So I called their customer service and discovered that our other option is to buy a higher ticket class so we can get a seat so that we CAN SIT WITH OUT UNDERAGE CHILDREN. Of course the "classic" class sets us back an extra $300 for a family of 4. A 26% premium over the economy ticket so we can be assured that our family isn't scattered all over the plane? No thanks.

It's a free market: I'll GLADLY spend more money on a different airline just to be rid of this bait and switch crap from Frontier. Good riddance, Frontier! All the cutesy animals on your planes will do nothing to change to fact that you're the bottom of the barrel.

Frontier's website and their customer service is appalling. I just tried to book tickets for over an hour on their website. I couldn't book the tix because my frequent flyer number wasn't recognized. Turns out after speaking to a customer rep, that the reason for that might have been b/c I have a hyphen in my last name although I have always been able to book tickets in the past with the same exact name and going through the exact same process. So, basically, their website was not working as it should have been. While spending 15 minutes on hold with the rep, I tried to rebook the flight only to find that the price had gone up by $46! So because of their website complications, I am being punished by having to pay $46 more. The manager said they couldn't do anything about giving me my initial ticket price--that I would need to pay the $46 more. It's too bad. We were this close to getting a free ticket with our frequent flyer miles. However, I'm completely willing to give that up and never fly Frontier again. Southwest has always had comparable fares with Frontier, so we're going to use Southwest now. I always had some local affection for Frontier since it was a Colorado company, but I am no longer a Frontier cheerleader. We're never flying Frontier again.

Have flown Frontier cross country twice in the past month and cannot say I had one bad experience. Six on time departures and six early arrivals. One arrival was 50 minutes ahead of schedule. Had a young person with me and the experience was rewarding. I will fly Frontier whenever I can and avoid United which has not treated me so well of late. Love the TV's.

THE worst. I was on a flight recently and was minutes from going into hypoglycemic shock yet the flight attendant refused to walk 11 rows to the food cart and get me a bag of M&Ms. I literally could have died in that plane. Once I would have lapsed into that coma, and nobody there knew to know the reason, I likely would not have recovered. Take a bus, ride a train, drive if you have to, but avoid this airline.

Flying to LAX from Denver for my wedding and their theif employees checked my bag, rifled through it and stole my brand new gps. We were unfamiliar with the roads in California. I have called several times and they refuse to help me and take no responsiblity. If they don't have survellience and can just steal everyone's items, what's to say they can't plant something in your bag. They need to have honest employees and have better ways of making them aware that they are being watched and they will be punished. That is just ridiculous. It definitely doesn't make me feel safe to have the luggage rummaged through to find that your things will be stolen!

They really need to make this right...I have been reading the reviews on many different websites and this is a HUGE problem. Lesson learned....NEVER fly FRONTIER and never check LUGGAGE! You guys are HORRIBLE!!!!!!!!!!!!!!!!!!!

ABSOLUTELY HORRIBLE. FRONTIER AIRLINE SERVICE
WE RACED ACROSS THE AIRPORT WITH 2 KIDS IN TOW. NO STOPPING JUST RAN FROM ON TERMINAL TO THE NEXT IN DENVER.
4 MIN LATE FOR CHECK IN TIME.
WE PURCHASED 5 TICKETS BUT WERE ONLY USING 4 AND THEY GAVE AWAY ALL OUR TICKETS, NO APOLOGY. NO REMORSE. SAID WE WERE 4 MIN FOR THE CHECK IN TIME. THE PLANE HADN;T EVEN LEFT YET.
WASN;T LEAVING FOR ANOTHER 15 MINUTES.
HORRIBLE TERRIBLE
THEN THEY SAID OUR LUGGAGE WAS ON THE PLANE.
PUT US ON A FLIGHT 6 HOURS LATER.
LOST ALL OF OUR LUGGAGE.
ITS BEEN 24 HOURS AND STILL NO LUGGAGE.
NO ONE HELPS.
BAD SERVICE
-NEVER EVER AGAIN.

Unbelievable! I used to love Frontier back when they were friendly, on-time, and competitively priced. That started going downhill, so I opted for other airlines. Then they went bankrupt. For some crazy reason, I decided to give them another try. Big mistake.

My fiance' and I flew from San Diego to Denver last week for some much needed R&R. The outbound leg went reasonably well. However, on the return leg, we arrived at the self check-in kiosk 42-43 minutes prior to the flight departure, which is past the required 45 minute limit. The kiosk guided us to the counter, where we again tried to print out boarding passes. A live person then tried to figure out what the issue was. Eventually we were told that we missed the deadline. With some polite prodding, the Frontier person called the gate and informed us that the gate would not let us proceed. Next she asked a manager, who didnt seem to care. We continued to plead our case, and then got another manager type who was quite rude and told us we should be on time in the future. We were issued stand-by boarding passes for the next day.

So our only recourse was to find a hotel room, as well as a pet sitter an additional night back home in San Diego. We go back to the airport bright and early the next morning, arriving at the gate one and a half hours prior to the first flight out. The polite Frontier person thought we had a good chance of getting on the flight, even though it was overbooked by one passenger. One of us would have been able to fly stand-by, but not the other. She put on stand-by for the next flight, two hours later, in positions one and two. She also related, after hearing our story of the previous night, that she would have let us through to board our original flight since we didnt have luggage to check.

We find out for the next flight that we have been bumped by four positions, no logical reason. This flight was overbooked by 3 or 4 passengers, and they were asking for people to take a later flight for vouchers. We missed that flight.

A polite Frontier customer service representative informed us that the next flight, at 12:35, had eleven empty seats and that we should be able to make it. For $75 each, we could confirm. I told her that would be adding insult to injury.

So we got two seats on the flight and made it home, approximately 17-18 hours later than planned. And I got to enjoy more comedy on that flight even before we left Denver late, as the able-minded Frontier personnel had doubled booked three of the six seats in an exit row. This led to repeated traffic jams with passengers as the double booked people stood in the aisle in the middle of the plane blocking both directions, oblivious to all.

Needless to say, I regret my decision to give Frontier another chance and am permanently removing them from my future travel plans. This experience is exactly the opposite of how a bankrupt business should be treating its customers (especially business travelers like me who fly 2-3 times a month).

If you are smart enough please take a Voice recorder with you and be prepared to start recording when you step in at the front desk.This recording might be helpful to you later.The front desk person harrased the customers along with us saying that you need to be 3 hours ahead for a domestic flight and so Frontier has the right to cancel your reservation.It was clearly understandable that he sold the tickets to others for more money.When you ask to show him the rules,You get an rude answer like ,Go look at the website.If you question strongly,he starts scaring you with the right to deny boarding coz of threat.When the next passenger comes in after an hour,he starts saying you should be 2 hours ahead and so on....Since we were on a fun trip to Vegas ,we didn't want to waste time arguing with this fellow.......He calls himself the manager @front desk.....So guyz if you plan to travel thru Frontier ,Gud Luck with this Front desk people.

I would give ZERO STARS if I could!

When we got to Las Vegas, my husband's bag had been rifled through -- all of his clothing was shoved to one side, which is very odd because he is an EXTREMELY careful packer. Anyway, a brand new dress shirt (still in packaging) and new watch (in its box) were both stolen. The cost of the items was about $350.

Frontier says: too bad. We take no responsiblilty. Basically, our employees can open your bags, take their pick of all your belongings, and you don't have any way to recover them.

They offered us a $75 travel voucher, but obviously we won't be flying with them again, since they employ and defend theives.

I know that some people will say that we our to blame for not locking our luggage, but last time I did that, the entire zipper of my suitcase was ripped out so that TSA could check my bag. So I guess you really can't win.

I bought a last minute ticket this week to attend a funeral for a dear family friend. The night before the trip I ended up in the ER with my 6 day old daughter who had a fever. It was incredibly scary for about 76 hours, and the last thing on my mind was canceling my ticket. 5 days later she is still in the hospital but stable so I had a minute to call about my missed reservation. Terry, a supervisor, told me too bad. no refund. no credit. Because I bought the so-called "economy ticket" which is anything but on a last minute flight, there was nothing I could do about it because that was the way their computer system worked. she was so smug and condescending she had the nerve to tell me that I had read the terms and conditions and I should have been aware of their policy. When I told her it was that kind of customer service that made the airline industry what it was, she told me Frontier had the best customer service in the industry. I am stunned.

I had the worse airline experience ever (both on the ground and in the air)! I will NEVER fly Frontier again, and advise everyone else to avoid them as well. After flying them this weekend, I can see why there are in bankruptcy, teetering on survival.

First, they moved the flight times three times in four months, making it difficult to plan when to pull my daughter out of the school early n order to make the initial departure flight.

Second, it really didn’t matter what time they said the times were because all four legs were late. The first outbound leg was delayed more than an hour while we sat on an airplane with no air conditioning or ventilation while the captain tried to correctly file the appropriate paperwork for us to depart. The flight crews were surly and clearly could not care less about customer service,

Third, I was hit with surprise baggage fees on the return from Las Vegas. When I booked the trip, I asked three different times if there were any luggage fees so I can compare the flight costs to other airlines like Southwest, and all three times were told there were not any luggage fees. And leaving Chicago, we didn’t have to pay anything for our luggage. But in Las Vegas, I was charged $15 for each bag (one for me, and one for my wife), and received a glib response from the attendant that either I pay the fees or just leave my bags behind.

Frontier airlines is the WORST domestic airline in the US. I missed a flight around Xmas time, and the people working at the counter were unprofessional and completely inept. Frontier could not get me on a flight the next day (after a wretched night in the airport), so I found a one-way fare on Southwest. On my return on Frontier, I inquired about the fact that I did not use the inbound portion of my ticket. I was told that I could use the amount as a credit for a future Frontier flight. Today I tried to use that credit, and I was told that I had to subtract a $150 change fee from that credit to use it on another Frontier flight! RIDICULOUS! I hope this airline goes bankrupt fast. They are pathetic.

Fly Southwest. So much better, friendlier staff, more appropriate rules and regulations.

I fly frequently due to work, and last year I was on Frontier for over 40,000 miles. I can say in all my trips, I was EARLY or exactly on-time all but 2 flights--and both of those flights were due to high winds at the Denver airport. Even with an hour delay, I still made it to my destination on time!

Frontier's planes are new, clean, and have good seats. They fly only Airbus jets (or the larger Q400 props (over 70 seats) for their smaller markets). No tiny 40 seat regional jets!!! The TVs make the flight go by faster. You only have to fly 15,000 miles to earn benefits as a frequent flyer. The flight crews have always been very nice and professional.

Most of the reviews on here seem to be from one-time, one-instance, infrequent flyers/passengers who are mad about something that either was out of anyone's control OR was their own fault (buying tickets for the wrong date, etc). Obviously no airline is perfect and Frontier has it's flaws, but then again, I can tell you from experience (flying millions of miles) that Frontier is way ahead of most other airlines in terms of customer service. Obviously if you buy the special, cheapest low-fare tickets, you will pay more to change them. I've never had a seating problem, nor any problems with flight crews. Honestly, the flight crews have handled some real jerks on board and maintained their cool.

Bottom line, I love Frontier and hope they expand their service. I feel more valued and appreciated at Frontier than at other airlines. I have nearly 7 million miles with another carrier and they don't acknowledge me any more than they do the first time passenger. If you want a flight on a clean plane with great service, Frontier is a great bargain.

In this day and age when we are struggling to make ends meet they charge $150 for a change fee.This is ludicrous. I have flown with Southwest for years. They are terrific! If you make a change there is no charge! I should have stayed with my gut adn stayed with Southwest! Frontier never again. I hope they do go out of business!

What an awful airline! I really hope they are the first airline to go out of business this year. The employees were all so rude, and cared very little about anyone on the flight. It was like a "sit down and shut up" attitude. On top of that, you have to pay for everything... checking baggage, food, TV. They always overbook flights. We ended up late getting there and coming back.

My family and I booked six seats from Washington Reagan National to Salt Lake City. Although we reserved six seats together, when we checked in, we were seated several seats apart from each other. When I told the check in agent that we needed to sit with our children, the agent said she couldn't do anything. I asked for a supervisor. There was none. I asked for their corporate number, but all I got was a recording that went to the same recorded loop no matter which option I selected. I have flown many airlines, but this is the worst domestic experience I have ever had. No wonder this airline is in bankruptcy. Their customer service is the worst and there reserved seats mean nothing.

The flight was late leaving one city because of something wrong with their plane causing many people to miss their connecting flights. After Frontier was very unhelpful to help find a flight. Even though it was Saturday and it was a major airport they told me I might have to wait until Monday to leave. I was supposed to be the first on stand by but people in line after me ended up getting tickets. I was surprised because I am always really nice to people. I am not a person to ever get upset because I understand how things happen out of control. Most people on Frontier were very rude and treated another lady's kid very bad. I could go on and on about how they treated everyone very bad. I hope I don't have to ever fly this airline again!

what a nightmare! the flight i paid for was delayed for 4 hours due to mechanical troubles, not weather. then the next connecting flight got me to my destination at 11:30 pm. they would not comp me a hotel and there were no rooms available anywhere near. the only other option was to take a taxi for 80miles to my friends house in the middle of the night. thinking that it could not get any worse, my bags were lost somewhere along the way. it's been 3 days now and i am without clean cloths or my hard drive which contained everything i needed for my work related trip. the woman in charge at the lost baggage counter could not have been less helpful and could barely speak english. at this point i almost feel embarrassed for them.
TIP: you get what you pay for. in my case though, i also lost about $2000 on top the charge for a less than par experience.
i am sure that once in a blue moon they arrive on time with everyones baggage, i have yet to have that luxury.
(the last time i flew frontier i was 2 hrs late and my bags were lost as well. they were delivered the next morning, this time it seems more permanent.)

Flight 148 (den)to (IAH) 7/22/08.Depart 8:35 pm. We arrived in Colorado and got seat number and gate only to find out that gate was changed to another gate within 2 minutes of being given the first gate number. Then they started loading the plane but had to stop cause not enough stewardesses on the plane so we had to wait 30-45 minutes for her to come to work! On landing in Houston, the pilot makes the sarcastic remark in a very countrified voice that "we are now at the George W. Buuuuuush airport! (obviously making fun of George W. Bush).I am a certified crane operator dedicated to keeping my people safe in whatever I am doing with a crane...so should a pilot think this way or quit his job. Some airlines are having hard times and some NEED to go broke. For the safety of all people, I think your airlines is one that certainly needs to go out of business.

I am a Summit member of Frontier airlines which is their highest status. I have really noticed a decline in performance. Their customer service agents, both at the counters and the phone are starting to act just like everyone else. If they are going to start treating their highest level members like crap, I might as well go to United, where I expect to be treated like crap but they have a much larger route network.

Frontier Airline is offer low price ticket but is not lowest price. This airline does not have any special program for senior people who usually have health concern and can cause change the trip any time. Let compare this Frontier Airline with Southwest airline + Fare Ticket: This compare at same time book ticket for 14 days advantage to travel date from Denver CO to Phoenix AZ for a senior person. - Frontier Airline: $69.59 (one way) - Southwest Airline: $59.99 (one way) + Exchange Fee: - Frontier Airline: $100 - Southwest Airline: $0 + Applicable fare difference - Frontier Airline: Assume you currently own a one way ticket with $175 credit, and now you change your mind and want to rebook to another fare * Travel to new fare with lower price: Example your new fare with a price ticket cost $88.60. This airline will charge you more $100 exchange fee and you lost the $175 - $88.60 = $86.40 difference amount. In this case if you agree to change your ticket will be cost $275 for the new fare. What do you think in this case? * Travel to new fare with higher price: Example your new fare with ticket cost $203.84. In this case you must pay more $128.84 ( $100 exchange fee + the fare difference $203.84 - $175 = $28.84) for this change, and the final price for the new fare is $303.84 - Southwest Airline DOES NOT charge you $100 exchange fee. You only pay the difference if you want to change travel to another fare with higher price ticket, and the Southwest Airline will keep the difference as your credit to apply to your next trip if you want to change to another fare with lower price. Hopefully this can help you save some $ and have fun trip

I flew Frontier Airlines for the first time August 2007 roundtrip from Houston to Las Vegas (stopping in Denver of course). This airline royally sucks. The flight crew was mostly rude and leg space is very limited. They don't serve any food. The biggest thing that pissed me off was on my way back I checked in four bags but somehow only three made it on the plane. I guess after they realized they're mistake the put the fourth bag on a Continental Airlines plane that was to arrive in Houston around the same time. Needless to say I have not received my bag. If I wanted my bag on a different airline, I would have flown on one. The bag contain a very sentimental gift for my kids that was to large for carry on. I was really looking forward to giving that souvenir to them after being away from them that long for the first time. Frontier f*ck it all up. I will NEVER fly them again. TAKE HEED!!!

Frontier Airlines was not helpful nor truthful about a delay on a flight from Orange County CA (John Wayne Airport, "SNA") to Denver and then on to Indianapolis on August 2, 2007. The flight was to depart at 8 p.m. We arrived and were checked in by 5:30 p.m. At ~ 7:20 p.m., with a "published" boarding time of 7:30 p.m., no one from Frontier was at the gate. We overheard another customer state that she was told that the flight would be delayed and that anyone making connections out of Denver most likely would miss the connecting flight. The "board" still read an 8:00 p.m departure time. With no Frontier agent/service availabe the "gate side" of Security, my husband went back out to the ticket counter as I tried to call Frontier. After 24 minutes and 12 seconds on hold, an agent responded on the phone, at the very same side my husband came through Security again and said he had been told the flight was cancelled. He was told we were rebooked on Continental on an Orange County (CA) to Newark NJ flight with a connection "BACK" to Indianapolis from Newark. We had to retrieve our luggage from Frontier, check in at Continental with our luggage, re-enter the Security line and get to the gate in ~ 15 minutes. Because of the way our tickets were issued by Continental, we were "randomly selected" for the thorough Security search.
Other Frontier passengers, who had Denver as their finsl destination, were told "the best I can do for you is a 9 a.m. flight tomorrow morning". The flight did finally leave CA at 10:00 p.m. arriving at Denver at 1 a.m. for those who were able to get on it.
Although we are happy that we did make it to Indianapolis by 8:45 a.m. (rather than the expected 5 a.m. arrival time we had hoped for), it was a grueling 5 hour nonstop to Newark NJ in a full Continental plane in middle seats and then a 2 hour flight back to Indianapolis.
At no point from the check-in at Frontier was there any attempt on their part to page passengers who had already checked in and alert them to the delay, possibly making some other arrangements possible.

Have always been on time for me, friendly staff....the guy at the check in counter was cracking jokes and doing voice impersonations and the individual TV's are cool.

Departing flight was 7 hours late due to mechanical failure. Frontier lied when they said they put me on another flight. Made me miss my connection in Denver. Unfortunately, no more flights were available that late at night. Frontier also refused to pay for a hotel. The hotel cost me more than the flight.

I recently flew from Chicago/Midway to Seattle via Denver on Frontier, and I could not have been happier. Friendly staff who were happy to help where they could, flights that left on time and arrived on time, plenty of entertainment options. I look forward to flying with them again.

Also, I am a frequent flyer member, and the booking rules for this are so easy-- I had no problem (and no extra cost) when I needed to switch a flight.

Here's all you need to know about Frontier: There's live TV from every seat (for $5), each plane has an animal painted on the wing that is promoted on the flight (Earl the Walrus!), the fares are pretty cheap.

If any of those things sound appealing to you, Frontier might be the airline for you.

Oh,where do I begin? I will start by saying that their policy and customer service is TERRIBLE! My son and I were going to the Seatac Airport so he could go to Denver. We arrived 1 hour prior to departure and were told the deadline for check-in is 45 minutes before departure. Well the lady,Billie,had an aditude to begin with. She was giving us a hard time about UMs [unacompanied minors] taking more time than "a normal check-in".So eventualy we asked for her supervisor's name and #. Then she said that we would try to make the flight well after the 45 minute deadline. She gave us the UM sheet and a 40$ fee and I said "I still want your supervisor's name and #".Then right after that she said " Ooopps,he can't go on this flight". So she called her supervisor as we were telling cutomers of Fronteir what we thought and knew about it. There was a guy who heard what she was sayingto the supervisor, then said "No she's not!"We waited about 2 hours for the supervisor! He gave us the hardest time! Needless to say we didn't make the flight so, DON'T FLY FRONTIER!

Frontier Airlines is a fairly new airline that is based out of Denver, CO. I personally found it to be the best airline to take while living in Denver. Their frequent flyer rewards program is actually useful and I was able to receive a free roundtrip ticket after about a year and a half of (alot of) flying. Their fares are reasonable, their cabin room is decent, a snack is provided and the flights are usually smooth. They even have a tv on the back of the seats to show you where your flying over and of course the usual $5.00 for directTv. The only downfall of this airline is that no matter where you fly you have to stop in Denver. Also international flights are limited to Calgary, Canada and Mexico and are expensive.

It is called a discount airline, but it reminds me of how pleasurable flying used to be. They actually serve food on flights, the seat pitch is nice, with more leg room, and to be able to fly nonstop somewhere these days is fantastic. Most B737's I have flown on are cattle cars, but the Airbus has more seat space. They do tend to change flight times more than I would like. Overall, I would be willing to pay a little extra to fly on a comfortable airplane non-stop.

Helmut, I'm glad for you on both counts.

I flew to Phoenix recently with this airline and was pleased with just about everything. The crew was friendly and we didn't crash. That's about all I'm concerned with.

I flew them from DC to Las Vegas (connected through Denver) and was VERY pleased with everything. Chatty, friendly crew, smooth flight, attentive service, and best of all, a small TV screen in the back of all seats. I am a geography buff and like to know what I'm flying over--and that navigational map was great. I don't need DirecTV to keep me entertained, but they offer it. And the planes are beautiful, inside and out. Love the animal pictures on the tails. Only drawback is not enough flights on the east coast, but I will fly them whenever I go west.

A great airline! I flew on business from Orange County to Denver, and it was way better than expected. The slogan now is that they use only new airplanes...and I have to say this airplace was beautiful. It was pretty roomy...much roomier than expected. Each cheap seat had its own LCD screen in the back of the seat in front of you, that showed DirectTV, as well as an up-to-the-minute naigational map showing your location on your route to your destination. I hate flying....because the turbulence bugs me. On this plane, I never noticed the small amount of turbulence, because I was so entertained. It was a super smooth flight, and the pilot made an excellently smooth landing. Staff was wonderful, and snacks were better than expected. Definitely much better than I ever expected!!!

This airline is only getting two stars because of their safety standard, both times I flew with this airline I always felt safe. But overall, this airline is bad. Rude flight attendants, horrid food (if you get any), no entertainment, and the seats are uncomfortable. I will never fly with this airline again, even if they do have cheap tickets...no thanks.

Frontier is great, and a lot less expensive than the major carriers. They're getting new planes, which should be a great addition. They don't usually have a lot of flights per day, so you might have to be flexible, especially if they cancel a flight. But I've flown them over twenty times and it has been a good experience every time.

I flew Frontier for my last two flights, and I had a good experience overall. One thing that stood out was how nice the flight attendants were. One woman even offered to carry my bag down the aisle of the plane, which has never happened to me before on another airline. On my flight to Las Vegas, the flight attendants organized an entertaining betting game. The snacks they served (hot pretzels with mustard, chips and salsa, and Wheatables) were tasty and and a nice change from the standard bag of peanuts. The only drawback was that one of my flights was delayed by an hour- hardly anything to complain about these days, though. I definitely plan to fly Frontier in the future whenever I can.
