LATAM Airlines Airbus A350-900 Seat Selection Guide (2026)

Quick Reference

Premium Business Class (2-2-2)

30 fully lie-flat seats in a 2-2-2 configuration across 5 rows. Every seat converts to a flat bed, but — and this is the key trade-off — window passengers do not have direct aisle access. You'll need to step over your neighbour or wake them up on overnight flights.

The seats are slightly staggered, with pairs angled towards each other with a low divider between them. This means couples in window-aisle pairs can interact easily, but solo travellers in window seats sacrifice privacy and aisle independence.

Best seats for solo travellers

• Aisle seats (B, D, G, J): Direct aisle access without climbing over anyone. The centre aisle seats (D, G) offer slightly more privacy than window-side aisles, as you have a console and divider between you and your neighbour rather than an open aisle.

Best seats for couples

• Window pairs (A/B or J/K): You're in your own two-seat pod against the fuselage. Intimate, easy to interact, and the window passenger only needs to step past their partner for the aisle.

Seats to avoid

• Row 1 (bulkhead): Smaller footwell, tray table in armrest (narrower seat), and proximity to the forward galley.
• Row 5 (last row): Close to the galley and lav zone between Business and Premium Economy.
• Any window seat (A, K) if you're solo: You'll be trapped behind your neighbour for the entire flight. On a 12-hour overnight GRU–CDG, this matters.

Premium Economy (2-3-2)

63 seats in 2-3-2 layout with extra pitch and recline compared to standard Economy. LATAM's Premium Economy is a step up with a dedicated cabin, enhanced meal service, and more space.

The 2-3-2 layout means the window pairs are great for couples, but the centre three seats include a middle seat — albeit with more width and pitch than standard Economy.

Best seats: Front-row window pairs for legroom and quiet. Avoid centre-middle seats (E position) if solo.

Economy Class (3-3-3)

246 seats in a 3-3-3 layout at standard long-haul pitch. The A350 fuselage is wider than a 787, so the 9-abreast Economy actually feels more spacious than 9-abreast on a Dreamliner.

LATAM+ and extra legroom

LATAM sells 72 seats with additional legroom under various brands: LATAM+, Front Row, and Exit Row seating. These are available for an additional fee and represent solid value on ultra-long-haul routes like SCL–SYD or GRU–CDG.

Best Economy seats

• LATAM+ / Exit row seats: Worth the fee on anything over 8 hours.
• Window seats in the A350's 3-3-3: The A350's wider cabin makes 3-3-3 feel less cramped than the same configuration on a 777.
• Front Economy rows: Less engine noise and first to be served.

Seats to avoid

• Last rows: Galley and lav proximity, reduced recline, and last to be served.
• Centre seats (E in any row): The universal Economy middle seat problem.

A350-900 vs 787-9: Which LATAM Aircraft Is Better?

This matters because LATAM operates both types on long-haul routes, and the experience can be very different.

In Business

• The A350-900 has 2-2-2 across the board — no version lottery, but no aisle access from windows.
• The 787-9 has a version lottery: newer aircraft have Thompson Vantage XL in 1-2-1 (much better — direct aisle access for everyone), while older aircraft have the same 2-2-2 layout as the A350.
• If you can identify a 787-9 with 1-2-1 Business, choose that over the A350 every time.

In Economy

• Both are 3-3-3, but the A350 fuselage is slightly wider, giving Economy passengers marginally more shoulder room.
• The A350 also has better cabin pressure and humidity than the 787.

Bottom line: For Business, try to get the newer 787-9 with 1-2-1. For Economy, the A350 is slightly better.

The Bigger Picture: LATAM's Fleet Retrofit

LATAM is in the middle of a $360 million fleet retrofit that's bringing new RECARO R7 suites with doors to the 787 fleet. Whether and when the A350 gets a similar upgrade is unclear — some A350s have been sold to Edelweiss (Swiss leisure carrier), suggesting LATAM may be reducing its A350 fleet rather than upgrading it. For now, the 2-2-2 layout is what you'll fly.
