Every Promise Frontier Has Made

“Frontier is committed to becoming the No. 1 low-cost carrier in the United States and will fill any gaps left by Spirit's exit.”

Frontier has expanded into former Spirit routes and markets. With Spirit's May 2026 shutdown, Frontier is the last major ULCC. However, Frontier's push into premium products (first class, lounges) is blurring its positioning as a pure low-cost carrier.

“Frontier will be the 'last man standing' in the ultra-low-cost carrier space. The ULCC model is alive and well.”

With Spirit ceasing operations in May 2026, Frontier is effectively the last major ULCC in the U.S. market. Biffle's prediction proved directionally correct. However, Frontier has also been pivoting away from pure ULCC with the introduction of first-class seats and premium products, blurring the definition.

“Frontier will introduce first-class seats in 2025 as part of 'The New Frontier' initiative — a promise to deliver exceptional value with unbeatable flexibility.”

Frontier announced first-class seats for 2025 delivery aircraft. The airline has been taking deliveries of new Airbus A321neo aircraft configured with a first-class cabin. Rollout is ongoing.

“Frontier does not use passengers' personal information to determine individualized pricing or fees.”

Senators Blumenthal, Hassan, and Hawley pushed Frontier and Spirit executives on personalized pricing practices. Frontier maintains it does not use personal data for individual price discrimination, but dynamic pricing based on demand patterns continues. No enforcement action has resulted.
