Delta retires 339‑seat A350‑900 and moves to 275‑seat premium‑heavy layout

Delta Air Lines operated three different cabin layouts on its Airbus A350‑900 fleet until late 2025, and the 339‑seat aircraft that came from LATAM flew its final Delta service on 25 October 2025 before being ferried to Singapore for reconfiguration.

The airline indicated that the entire A350‑900 fleet will be standardized on a 275‑seat premium‑heavy layout, which adds 40 Delta One suites compared with 32 in the standard 306‑seat configuration and removes 31 seats overall.
