ATA Airlines said its decision to leave Chicago's Midway Airport starting next month will not affect its scheduled flights to Hawaii from Oakland, Los Angeles, Phoenix and Las Vegas.

Citing high fuel prices, the company said yesterday it will stop its domestic flights out of Midway on April 14 and its international flights to Mexico on June 7.

"This was a difficult decision, but the high cost of fuel has made it economically unfeasible to continue our low-fare service at Midway," said Rob Binns, ATA's chief commercial and planning officer, in a statement released yesterday.

ATA emerged from federal bankruptcy protection in 2006 and is now a subsidiary of Global Aero Logistics Inc.
