Delta Q3 revenue climbed 12% year-over-year as Delta Air Lines (DAL) pointed to strong transatlantic and domestic demand and announced a $500 million airport hub investment.

Delta reported improved passenger revenue in the third quarter of 2025, driven by demand across domestic routes and transatlantic markets. The carrier said the boost reflects resilient travel demand and higher yields on international services, helping push passenger revenue up 12% versus the same period last year.

What Delta Q3 revenue means for hubs

The $500 million commitment will be spent on airport infrastructure upgrades at Hartsfield–Jackson Atlanta International Airport (ATL), Detroit Metropolitan Wayne County Airport (DTW) and Seattle–Tacoma International Airport (SEA). Delta says the work is intended to improve the passenger experience and operational efficiency across terminals, gate areas and ground systems.

Delta Air Lines (DAL) framed the investment as targeted, network-level support to reduce pinch points during peak travel and to modernize key customer touchpoints. While the airline did not publish a line-by-line budget breakdown, the announcement signals continued airline investment in airport assets as part of its broader network strategy.
