History of Frontier Airlines' destinations

The history of Frontier Airlines dates back to November 27, 1946, when Monarch Air Lines began service in the Four Corners states of Colorado, Utah, New Mexico, and Arizona. In 1950, Frontier Airlines was formed by the merger of Arizona Airways, Challenger Airlines, and Monarch Air Lines. The airline was headquartered at the now-closed Stapleton International Airport in Denver, Colorado. Between 1950 and 1986, Frontier Airlines served destinations across the United States, including Montana, Wyoming, Washington D.C., St. Louis, Houston, and Saskatoon, Saskatchewan, Canada. By 1979, the airline served 94 cities in 26 states, Canada, and Mexico.

In 1994, a new airline using the Frontier Airlines name was founded. The airline began scheduled flights on July 5, 1994, between Denver and four cities in North Dakota. By January 1995, Frontier had expanded its route network to include destinations in New Mexico, Montana, North Dakota, Texas, Nevada, Nebraska, and Arizona. In 1997, Frontier accused United Airlines of "dumping" and other antitrust violations.

In 2012, Republic Airways Holdings announced its intention to sell or spin off Frontier Airlines. That year, Frontier started low-frequency service between Orlando International Airport and Trenton–Mercer Airport in New Jersey. In July 2013, Frontier expanded its service to Wilmington-New Castle Airport near Wilmington, Delaware, marketing it as Wilmington/Philadelphia.

In 2015, Frontier cut several flights from Wilmington and Trenton and ceased operations in Wilmington in June 2015. That year, the airline also expanded its service from Atlanta, adding it as a focus city. In 2016, Frontier re-established service to John Glenn Columbus International Airport and launched new service to Havana, Cuba, from Miami, Las Vegas, and Denver. In 2017, Frontier began serving Buffalo, New York, with service to Denver, Colorado, and Florida. In 2018, Frontier and Volaris, a Mexican low-cost carrier, began a codeshare agreement.

As of March 2025, Frontier Airlines departs from 109 airports in 15 countries. The airline has continued to expand its destinations and routes, including the addition of a crew operating base at Dallas Fort Worth International Airport in 2023.
