US Airways is shutting down its affiliate carrier MidAtlantic Airways on May 28th. This follows a growing trend with the major airlines going back to independent carriers for its feeder airlines. Delta has sold its ASA division to SkyWest and is in a very contentious negotiation with ComAir presently. With the MidAtlantic Airways shut down, 368 employees will be laid off.

MidAtlantic Airways will stop operating May 28, the company said Thursday. Seventy-eight workers will be laid off in Pittsburgh, with the rest of the cuts coming in Philadelphia.
The express service, intended as a feeder airline for US Airways, was launched with great promise in May 2002, when Potomac Air was revived and renamed. Based in Pittsburgh, the division flew Embraer 170 regional jets with 72 seats to six Eastern U.S. destinations.
The closing of the regional jet unit had been expected. US Airways sold the assets of MidAtlantic to Indianapolis commuter carrier Republic Airways during its last bankruptcy. via the AP Wire
