Delta A350-900 Seat Selection Guide (2026)
Delta operates two distinct versions of the Airbus A350-900:
- Delta One Suites A350 (Standard DL Configuration) — Features Delta One Suites with doors, Premium Select, and a 3-3-3 Economy layout. This is the most common version across the long-haul fleet.
- Ex-LATAM A350 (Non-Suite Version) — Acquired second-hand. Features a different Business Class seat (no door), a different Premium Economy section, and slightly different row numbering. These aircraft operate select Asia and trans-Pacific services.
Because the two aircraft appear on overlapping routes, travellers should always confirm their configuration.
Row numbers vary slightly between versions. All ranges below are approximate.
1. Quick Verdict
Choose the Delta One Suites A350 whenever possible — it is Delta's best long-haul seat.
In Delta One Suites, the best seats are the true window suites (A/D) in odd rows 3, 5, and 7 for solo travellers, or centre pairs (B/C) in rows 2–7 for couples.
Premium Select is consistently strong across both versions; row 21 window pairs are the sweet spot.
In Economy, choose the Comfort+ bulkhead row or forward Main Cabin for the quietest experience.
