Overview
- Frontier unveiled 20 routes launching from late 2025 into early 2026, centered on Fort Lauderdale, Detroit, Houston, Baltimore, Charlotte, and Dallas.
- All but two of the new routes mirror existing Spirit service, and Frontier now overlaps Spirit on about 35% of its capacity, the highest overlap of any airline.
- Introductory one‑way fares start at $29, and the carrier is offering loyalty‑matching promotions to attract competitors’ customers.
- CEO Barry Biffle declined to discuss mergers and said he expects Frontier would capture most of Spirit’s market share if the rival collapses.
- Spirit recently drew its entire $275 million revolving credit line after cautioning about its ability to continue operating, as Spirit posted a roughly $246 million Q2 loss and Frontier reported a $70 million loss.
