Leaving Sat and just found out USAir cancelled our flight to Orlando! Contacted Expedia as to why we were not notified of a change and they said "when an airline has a mass cancellation our computer system won't process it". Well after 6 hours of scrambling to make new arrangements we managed to secure a flight for the same morning from a different airport but just barely. So a friendly warning to fellow flyers, please check with the airline directly concerning cancellations if you originally used Expedia to purchase tickets. Also we had e-tickets and had to go directly to the airport to pick up the new tickets in advance.
