Thousands of AirTran customers spent hours in line at Atlanta’s airport and flights went out nearly empty due to a balky new computer system. Guess what OS it runs?

According to the Atlanta Journal-Constituion article AirTran issues a $100 apology:

AirTran replaced software that controls functions such as reservations and passenger check-ins with a new Windows-based system. The new system was expected to handle more transactions and to give the fast-growing airline more flexibility to add more features in the future. The company said it spent years planning the change to a new system and months testing and revising the software after Minneapolis-based Navitaire said it no longer planned to maintain the old system.

AirTran’s my favorite airline, but now that I know that flying them makes me rely on Windows software that’s proven to be a catastrophic failure… maybe I’ll take a chance and look at Delta again.
