Air Midwest began filing notices with the Department of Transportation (DOT) of its intent to terminate EAS beginning over a year ago. "Although we are unable to continue to provide service, Air Midwest plans to cooperate with the DOT and any replacement carriers in the interest of lessening the impact on the communities affected," said Greg Stephens, Air Midwest's President.

Air Midwest will shut down based on the following schedule:

"We are extremely saddened this decision has become necessary; Air Midwest has a long and proud history and has served millions of passengers in its 43 years of operation," said Jonathan Ornstein, CEO of Mesa Air Group. "Unfortunately under the current economic conditions there was no foreseeable way to achieve sustained profitability. Even with subsidies from the DOT, Air Midwest has been unable to sustain profitability for the last several years. While this was an extremely difficult decision, and one that the company worked tirelessly to avoid, we are working diligently to minimize the impact this decision will have on Air Midwest's passengers and employees."
