DO NOT USE THEM. I've spent roughly 20 hours on the phone trying to deal with issues caused by their system. Today, I have spent 4 hours on hold and have yet to talk to someone who can help me. The first, they ripped me off by 1000$, the second they booked the wrong flight dates. No one is taking responsibility for the charges, Visa has cold feet about issuing a chargeback. This is a horrible experience. My advice if you are stuck dealing with them: *force* your credit card issuer to perform a chargeback on the transactions.
