All Delta Air Lines 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.

Where Delta Air Lines dominates

Delta Air Lines carries a commanding share of the passengers at its fortress hubs — a clearer read on its power than raw fleet size. Share is of every carrier's passengers at that airport, including its regional feeders; on time is that hub's own arrival rate.
