HONOLULU — ATA Airlines announced  that it has canceled all future flights. ATA Airlines filed for bankruptcy on Wednesday because of financial problems. The Indianapolis-based, low cost airline said it loss a key contract for military charters.

“We deeply regret the disruption and hardship caused by the sudden shutdown of ATA, an outcome we and our employees had worked very hard and made many sacrifices to avoid. Unfortunately, the cancellation of a critical agreement for our military charter business undermined ATA’s plan to address the current conditions facing all scheduled service airlines, including the tremendous spike in the price of jet fuel in recent months. As a result, it became impossible for ATA to continue operating,” ATA Chief Operating Officer Doug Yakola said in a written statement.

ATA averaged about 15 flights daily to and from Hawaii from Phoenix, Los Angeles, Oakland, Calif.; and Las Vegas and employed about 50 people locally.

People who purchased tickets from ATA using a credit card can contact their credit card company for more information about how to get a refund for unused tickets.
