I've been really disappointed with the service and will never book another flight with them: the transaction was ok, I received a confirmation, and suddenly, a few days later, I received another e-mail, of cancellation, this time, saying that I was the one who cancelled the flight! I then tried to call them. They made me wait for more than one hour on the phone and they finally just hung up on me! When I tried once more, it was really difficult to get the right department, everybody redirected me to other dpts. When finally I got someone real and ready to answer my questions, I tried to know what happened -maybe my credit card hadn't been accepted?- but there was nothing wrong! They just cancelled without any reason and, of course, the new best fare they could offer me was much more expensive than the initial one! I had to restart all the process of on-line booking... with another agency!
CheapOair: never again!
