Frontier Airlines — Company Profile & Interview Intel

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.
