Cheap Midwest Airlines Flights (YX)

Midwest Airlines (formerly Midwest Express) was a U.S.-based airline and was also an operating brand of Republic Airways Holdings based in Oak Creek, Wisconsin. It was operating from Milwaukee's General Mitchell International Airport. On April 13, 2010, parent company Republic announced that Midwest Airlines and Frontier Airlines will merge, with the Midwest brand disappearing in the fall of 2011.

On April 13, 2010, Republic announced that the Frontier Airlines name would be kept. Parts of the Midwest brand will be incorporated into the Frontier brand as part of the merger, namely the iconic Midwest cookie and the slogan of Midwest Airlines, "The Best Care In The Air."

Midwest Airlines' final flight operated with a Boeing 717 and staffed with Midwest Airlines flight crews landed in Milwaukee on November 2, 2009. Effective November 3, 2009, Midwest Airlines ceased to exist as an actual operating airline.

According to media reports, only very few employees have moved over from the previous Midwest umbrella to the new Republic Airways/Frontier company.

However, the airline continued to operate using the same branding, livery and a very similar route structure. Flights were operated by Republic Airlines and Frontier Airlines flightcrews.

The Milwaukee hub and base was maintained along with the Kansas City hub. A new focus city was started in Omaha.
