Air Wisconsin Airlines is a regional airline based at Appleton International Airport in the town of Greenville, Wisconsin, near Appleton. Air Wisconsin originally operated as one of the original United Express partners in 1985, and operated then as US Airways Express on behalf of US Airways prior to becoming an American Eagle regional air carrier. Between March 2018 and April 2023, Air Wisconsin operated exclusively as a United Express regional air carrier once again with primary hubs located at Chicago's O'Hare International Airport (ORD) and Washington Dulles International Airport (IAD). This came to an end in April 2023 as the carrier switched to conducting solely American Eagle branded flights, per a new contract with American Airlines.
Continental Express was the operating brand name used by a number of independently owned regional airlines providing commuter airliner and regional jet feeder service under agreement with Continental Airlines. In 2012 at the time of Continental's merger with United Airlines, two carriers were operating using the Continental Express brand name:
America West Express was the brand name for America West Airlines commuter and regional flights operated by Mesa Air Group's Mesa Airlines under a code share agreement. Today Mesa Airlines operates for American Eagle.
US Airways Express was the brand name for the regional affiliate of US Airways, under which a number of individually owned commuter air carriers and regional airlines operate short and medium haul routes. This code sharing service was previously operated as USAir Express. Mainline carriers often outsource to regional airlines to operate services in order to increase frequency, serve routes that would not sustain larger aircraft, or for other competitive reasons. US Airways Express operations were conducted from smaller markets in the United States, Canada, and the Bahamas primarily centered on US Airways' major hubs and focus cities. Upon the completion of US Airways' merger process with American Airlines, US Airways Express was rebranded as American Eagle on October 17, 2015.

Intrastate airlines in the U.S. are defined as air carriers operating inside of one individual state and thus not flying across state lines. Larger intrastate airlines in the U.S. that operated mainline turboprop and/or jet aircraft were created as a result of former federal airline regulations, as passenger air carriers that only flew intrastate service were not regulated by the federal government but were instead primarily regulated by the respective state governments in their home states. For example, Pacific Southwest Airlines (PSA) and Air California were both regulated by the California Public Utilities Commission (CPUC) prior to the federal Airline Deregulation Act of 1978. Although intrastate airlines in some states used only turboprop aircraft, scheduled passenger service on jet aircraft was operated by intrastate air carriers in California, Florida, Hawaii and Texas.
