This performance report includes operating statistics for the 50-seat regional jet fleet operated by SkyWest Airlines, affecting year-over-year comparisons for Midwest Air Group and Midwest Connect. That service, which launched April 1, 2007, has allowed for the opening of new markets as well as the conversion to Midwest Connect of some flights previously flown by Midwest Airlines.

Readers of Travel+Leisure named Midwest Airlines “Best Domestic Airline” in the magazine’s 2007 World’s Best Awards competition. The airline features jet service throughout the United States, including Milwaukee’s most daily nonstop flights and best schedule to major destinations. Catering to business travelers and discerning leisure travelers, the airline earned its reputation as “The best care in the air” by providing passengers with impeccable service and onboard amenities at competitive fares. Both Skyway Airlines, Inc. — a wholly owned subsidiary of Midwest Airlines — and SkyWest Airlines, Inc. operate as Midwest Connect and offer service to and connections through Midwest Airlines’ hubs. Together, the airlines offer service to more than 50 cities. More information is available at http://www.midwestairlines.com/.
