allegiant air is a terrible airline. my sisters were flying from medford to pheonix the airplane was having engine problems in pheonix and couldnt take off so with it being monsoon season the other flight had to wait on the tarmac for an hour so they could get off the plane and wait for a new plane. the delay went from 4 hours to 5-6 hours. their staff at the airport told us that we could go home but we needed to be back at the airport by 11 pm. we live 45 minutes away from the airport so we decided to just go home if it could be up to 6 hours! the original flight was actually set to depart at 8 pm. when we got home we called allegiant air and a machine told us to check on their website where there flights staus was "unavailable" after calling again and waiting to talk to someone as the waiting time kept getting pushed back the lady we talked to had no knowledge of the enigine trouble and 6 hour delay we were talking about so after putting us on hold again she came back to the phone just to say she had no further information.there goes 30 more minutes! we arrived at the airport directly at 11 to find that there was no one at the allegiant air counter. when a man did come all he had to say was we have no information about the flight. when they did recieve inforation about it we were told to be back at the airport by 140 AM because the plane would leave at 245 am. after the 7 hour wait the plane did finally come in and land, it took an hour before anyone even got on the plane, and when they did it was a different plane then the original had been and nobody had a seat because they had messed up the seating arrangement too. after the flight took off a gentleman was telling us that the exact same problem with the engine and the delay happened just a week ago on the same pheonix medford flight. we ended up paying for a 5 hour parking ticket and 120 miles of gas just because of the airlines mistake!!!!ALLEGIANT AIR IS NOT A GOOD AIRLINE!!!!!i would strongly suggest not using it. if the reason you want to is because of pirce, its a scam they make the ticket cheap but you have to pay for everything else!!!! 2 dollars for a sode that united would give you complimentary? you also have to pay extra for your bags and if you want a seat that is yours and yours only.they are dirty smelly and cramped, allegiant air sucks.
