We tried to change our flight schedule 72 days before departure. They wanted $250 per ticket (family of 4) on top of the fees that the airline would charge. I am currently disputing the original charge for the tickets with my bank in hopes that I can get my cash back from Orbitz. I am willing to pay a fee to reschedule my flights. It's only fair. But, $300+ per ticket (Orbitz plus United's fees) is insanity for what amounts to a few clicks on a computer screen. For a family who gets but one vacation every 1-2 years, this is upsetting. I can say with 100% certainty, that I will NEVER use Orbitz again. I learned an expensive lesson.
