Mesa Air Group Inc., a U.S. commuter airline that flies for larger carriers and has several routes in Utah, said it expects to report a loss for the fiscal year that ended in September.

The results will be delayed pending a review of "certain estimates," Phoenix-based Mesa said in a regulatory filing Friday. The airline fired Chief Financial Officer George "Peter" Murnane last month and named William Hoke as interim CFO after a probe into possible misconduct.

The airline notified regulators of the delay a day after losing a bid to overturn an $80 million damage award it was ordered to pay Hawaiian Airlines Inc. for using confidential information to set up a competing carrier.

Mesa's expected 2007 loss would compare with a profit of $34 million, or 84 cents a share, in fiscal 2006, according to the filing.

The carrier operates regional flights for Delta Air Lines Inc., US Airways Group Inc. and United Airlines. It makes more than 1,100 daily flights to 184 cities in the United States, Canada, the Bahamas and Mexico.
