All Frontier Airlines routes, hubs & monthly capacity

Bars are seats added or cut; the figure is the percentage. Comparing August 2025–July 2026 against August 2024–July 2025. Routes the airline started or dropped mid-year are left out — a percentage between a partial year and a full one measures whether the route existed, not how its capacity changed.

Frontier Airlines hubs & focus cities

Frontier Airlines spreads its flying across 8 bases rather than funnelling it through one fortress. Share is of every carrier's passengers at that airport, including its regional feeders; on time is that hub's own arrival rate.
