What do you do if you have a flight planned on one of the three airlines, ATA, Champion and Aloha, that filed for bankruptcy and terminated all flights this week? First thing to do is if you paid with a credit card company, call them up and ask for a refund. An ATA insider tells us, “When an airline bills you for your ticket, they don’t receive payment–the money’s escrowed until you fly or the terms of the contract are met, i.e. one year validity limit, so the bankruptcy doesn’t affect those customers.” Elliot.org has the run-down of other options: On the press release level, United Airlines has agreed to take on Aloha Airlines passengers, but anecdotal evidence suggests the ground-level customer service reps are bungling the hand-off. Southwest has agreed to rebook ATA passengers, but the language suggests this deal is only good for flights that were codeshares between the two airlines. Lastly, if you bought your ticket with ATA by check or cash, you can claim a refund, for probably a fraction of its value, after the airline is liquidated.
