Chapter 11, bankruptcy has been filed by U. S regional air line operator, Mesa Air Group Inc. at U. S. Bankruptcy Court.

Mesa’s operations include Delta, United and US Airways.

Currently Mesa’s fleet size is of 130, out of which 52 planes are not being used and 25 are to be retired. This will help Mesa to reduce retaining and maintenance expenditure for extra aircrafts.

Mesa's Hawaiian Joint venture, go!-Mokulele is not associated with this filling and it will continue its operations.

Ample liquidity with Mesa will help it during its restructuring and its 3,400 employees will continue to work during this phase.

In an application filled on 30th September, 2009, Mesa quoted its assets worth $975 million with liabilities of $869 million.

Company is already claiming $70 million from Delta, in a law suit filled for the damages occurred due to cancellation of agreement by the former in 2008.

As of now Mesa operates 700 daily departures to 127 cities in U. S., Canada and Mexico.

For the last fiscal year, 96 percent of the Mesa’s total revenue, $968 million, was the consolidated passenger revenue, which was generated through "revenue guarantee" agreements among all partners.

64 percent fall in Mesa’s shares has been recorded in the pre-market trade on Tuesday closing at 4.25 cents.
