Frontier Airlines

Big-picture snapshot

Frontier Airlines is an ultra-low-cost carrier operating an all-Airbus A320-family fleet of approximately 162-176 aircraft across 14 domiciles. It is headquartered in Denver, Colorado, and employs approximately 2,044-2,260 pilots represented by ALPA. James G. Dempsey became President and CEO on January 8, 2026, replacing Barry Biffle who departed after 11 years.

For interview purposes, the simplest way to frame Frontier is this: it is Indigo Partners' ULCC platform — a publicly traded (NASDAQ: ULCC) ultra-low-cost carrier with the second-largest all-Airbus narrowbody fleet among U.S. ULCCs. Frontier is in the middle of a significant fleet right-sizing (returning 24 A320neo aircraft in Q2 2026 while deferring 69 deliveries) and a CEO transition. The pilot contract has been amendable since early 2024, with negotiations stalled for 18+ months and pilots having voted to authorize a strike. Frontier offers a 12-15% A/B fund retirement contribution — among the best in the ULCC segment — and competitive Year 1 FO pay at $100/hour.

Business model

Frontier operates as an ultra-low-cost carrier — the same model as Spirit and Allegiant, but with a more hub-oriented approach:

• ULCC model: Extremely low base fares supplemented by ancillary revenue from bags, seat selection, priority boarding, and other add-ons.
• Hub-ish operations: While ULCC by model, Frontier operates a quasi-hub structure from Denver (DEN), Atlanta (ATL), and Orlando (MCO) — three airports with the highest daily departures.
• All-Airbus fleet: A320ceo, A320neo, A321ceo, A321neo — all narrowbody aircraft in high-density configurations.
• Domestic and international: 81 domestic destinations and 18 international destinations in 13 countries (Mexico, Caribbean, Central America).
• Indigo Partners ownership: Indigo Partners, led by aviation investor William Franke, controls Frontier through its majority stake. Franke also has investments in Wizz Air (Europe), Volaris (Mexico), and JetSMART (South America).
