Do yourself a favor and do not use this service. They booked me on the wrong flight and tried to blame it on the airline. I was standing in line to board the flight when I was told I was not on the manifest, yet I had a written confirmation from CheapOair that I was. They kept me on hold for 3 hours, (they hung up on me twice so I had to call back), trying to find out whose fault it was rather than rebooking me on a flight. I actually only saved a few dollars by using this service. I wish I had spent the extra $40 and booked directly with American. The best thing they can do for you mentally is to refer you to another service.
The airline had a change in schedules, and had not notified us, therefore we could not extend the changes to the customer in a timely manner. However, this was resolved that day! Our apologies for the inconvenience,.
