Q. I recently got a really great deal on Orbitz flying American Airlines.  Problem is I need to change the dates on my tickets.  I read the news today that Orbitz is no longer selling tickets for American Airlines.  Is my ticket still valid?  How can I make any changes?  Why did American remove their fares from Orbitz?

A. Yes, your ticket is still valid.  Orbitz is no longer selling American tickets as of December 21, 2010.  If you bought the ticket before that date, it will still be valid.  However, if you need to make any changes to your itinerary, you'll have to contact AA reservations at 1-800-233-7300.  More information can be found here.  And why?  We'll tell you why.
