Frontier Airlines

Frontier Airlines, headquartered in Denver, Colorado, is a major American ultra-low-cost carrier operating flights to over 120 destinations across the United States, the Caribbean, Mexico, and Central America.

Established on July 5, 1994, Frontier has grown to become one of the largest ULCCs in the U.S., employing more than 7,000 staff members.

Fleet and Sustainability

The airline's fleet comprises 163 Airbus A320 family aircraft, including the A320neo and A321neo models. This makes it the largest and youngest A320neo family fleet in the U.S.

This modern fleet contributes to Frontier's commitment to fuel efficiency and environmental sustainability. In 2024, the Centre for Aviation recognized Frontier as the North American Environmental Sustainability Airline of the Year.

Business Model and Seating

Frontier's business model focuses on providing low fares with optional services for additional fees such as seat selection, baggage allowance, and in-flight refreshments.

The airline's seating configuration features all-economy class with a 3–3 layout and offers "Stretch" seats with extra legroom for those seeking additional comfort.

Network Strategy

In recent years, Frontier has restructured its network to focus on higher-fare markets like Seattle and Detroit while reducing its presence in leisure destinations like Las Vegas and Florida.

This strategic shift aims to improve earnings and tap into growing demand for premium travel by increasing availability of seats with extra legroom and targeting business fares for small companies.
