Overview
- Frontier unveiled 20 routes launching from late 2025 into early 2026 from hubs including Fort Lauderdale, Detroit, Houston, Baltimore, Charlotte and Dallas, with limited weekly frequencies.
- Introductory one-way fares start at $29 on select routes, with examples including Fort Lauderdale–Detroit/Chicago/Charlotte/Houston and Houston–Guatemala City/San Pedro Sula/New Orleans.
- Frontier and Spirit overlap on roughly 35% of capacity, and Frontier says the additions support its push to be the top low‑fare carrier in major U.S. metros alongside new loyalty-matching and product upgrades.
- Spirit disclosed a going‑concern warning on Aug. 11, posted a $245.8 million Q2 loss, drew its full $275 million revolver, agreed to higher credit‑card holdbacks, and is cutting flying and furloughing pilots.
- Frontier’s CEO said most of the new markets are currently served by Spirit and projected Frontier would capture a majority of Spirit’s share if the carrier fails, with only two new Houston routes not on Spirit’s map.
