making the reservation for flights and a vehicle go ok, but if you need to make any changes, that's where things go sideways! I called three times, explaining that I needed to make a change to my car rental plan, and each time I was sent to an extension that was no longer valid according to the recording I kept getting! Each time I called back, I explained I was getting sent to an extension that was no longer valid and she would briefly apologize and say hold on and then send me again to an extension that was no longer valid! I finally had to call the car rental agency itself and make changes through them, it could not be done through this cheap flight fares site at all.
