Best Seats on Boeing 787-9 Dreamliner

Overview

The Boeing 787-9 Dreamliner is one of the most passenger-friendly widebody aircraft ever built. Stretching 206 feet and seating 250–320 passengers across typically three classes, it introduces game-changing technologies: composite fuselage that allows higher cabin humidity (15–20% vs 5–8% on older jets), cabin pressure equivalent to 6,000 feet altitude instead of 8,000, and electronically dimmable windows that eliminate the need for window shades.

Economy class features a 3-3-3 layout with seat width of 17–18 inches and pitch of 31–32 inches on most carriers. Premium economy typically offers 3-3-3 or 2-4-2 at 38–40 inches pitch. Business class varies dramatically by airline, from lie-flat pods to herringbone suites.

Business Class Best Picks

The 787-9's business cabin is where configurations diverge most dramatically between carriers. Here are the best picks by airline:

• United Polaris (1-2-1): All aisle-access seats in a herringbone layout. Seats 1A, 2A, 3A (window, direct aisle) are the gold standard. Avoid the center seats (e.g., 2D, 2G) — you'll be sleeping head-to-head with a stranger.
• Air Canada Signature Class (1-2-1): Direct aisle access throughout. Row 1 (1A, 1K) offers privacy at the front. Bulkhead rows have more floor space but limited privacy.
• Singapore Airlines Business (1-2-1 or 2-2-2 on some frames): The 787-9 frames with 1-2-1 staggered layout give every seat direct aisle access. Seats in the mini-cabin (rows 11–12) feel more intimate than the main cabin.
• JAL Sky Suite (2-2-2): The center pairs (e.g., 8D, 8G) are excellent for couples. Solo travelers prefer aisle-side window seats like 8A or 8K.

Premium Economy Guide

The 787-9's premium economy cabin is one of the best values in commercial aviation, particularly on long-haul routes. Standard configuration is 2-3-2 or 2-4-2 with pitch ranging from 38 to 42 inches and width of 19–20 inches.

• Best seats: Window seats in the first premium economy row (often row 20 or 21) give extra legroom from the bulkhead, storage in the divider wall, and an unobstructed recline.
• Avoid: Last row of premium economy — recline is limited to avoid impinging on economy class, and galley noise bleeds back.
• United Premium Plus (Row 21–24): 2-4-2 layout. Seats 21A and 21K are the best — extra bulkhead legroom, window views, and no one in front of you.
• ANA Premium Economy: Notably wide (19.4 inches) with a seat shell that isolates you from neighboring seat movement. Rows 27–30 in most configs.

Economy Best Seats

In economy's 3-3-3 configuration, seat selection significantly affects comfort:

• Bulkhead row (first economy row): Extra legroom, but no under-seat storage. Best for tall passengers who don't need to access bags during flight.
• Rows 3–6 of economy cabin (window): Away from wing noise, good window views, fast deplaning. Seats like 33A or 35K (depending on config) are consistently top-rated.
• Center seats in middle section (e.g., 40E, 40F): Surprisingly good for solo travelers — only one neighbor per side rather than being sandwiched between two strangers.
• Avoid last 3 rows: No recline, lavatory proximity, last to board and deplane.

Window Dimming Feature

The 787-9's electrochromic windows are one of its signature features — passengers press a button to cycle through five tint levels from fully clear to nearly opaque. This means:

• Window seats are more enjoyable on the 787-9 because you can always dim the light without losing the view entirely.
• The crew can override individual window settings from a galley panel — on some flights they force all windows to the darkest setting during sleep periods.
• The windows are also notably larger than 777 or A330 windows, improving the view from middle-section window seats.

Given these advantages, window seats are strongly recommended over aisle seats on the 787-9, especially for scenic routes over mountains, oceans, or polar regions.
