Frontier Airlines

Frontier Airlines is an American ultra-low-cost carrier founded in 1994 and headquartered in Denver, Colorado. Listed on NASDAQ under the ticker ULCC, the airline reported $3.7 billion in revenue in 2025 and carries 33 million passengers a year. Its business model rests on low base fares supplemented by optional services that customers can add as they choose, a proposition the company describes as "Low Fares Done Right".

The carrier operates more than 100 Airbus A320 family aircraft, including the largest A320neo fleet in the Americas, powered by Pratt & Whitney GTF engines. High-density seating configurations, weight-saving measures and fuel-efficient fleet management underpin what the company describes as the most fuel-efficient fleet among major U.S. carriers. The network spans over 440 nonstop routes across more than 100 airports, serving destinations in the United States, Mexico and the Caribbean, with up to 700 flights a day.

Frontier employs more than 5,000 team members. Technical work touches aviation operations, aircraft engineering on the A320neo family, seating configuration design and loyalty programme technology supporting FRONTIER Miles. The company continues to expand its route network and markets itself as "America's greenest airline".
