The KLM Royal Dutch Airlines Boeing 777-300ER carries 381 passengers across Business + Premium Economy + Economy. Power and Wi-Fi are available on this aircraft. Every seat is rated below, so you can see which have the legroom, the window alignment and the quiet — and which sit next to a galley or lavatory.
The seats rated best on this map are 2A, 3A, 3K, 4A, 4K, 5A. Another 79 seats are rated best or good. Look for 38 extra-legroom seats for the most room.
Seats rated avoid on this map are 20C, 20D, 20E, 20F, 20G, 20H. Another 54 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
Over 300 seats are in the economy cabin, arranged three-four-three abreast across a long fuselage. That means many rows and a real difference between front-of-cabin and rear-of-cabin positions for boarding, deplaning, and galley proximity.
Yes. The one-two-one reverse-herringbone layout gives every Business seat direct aisle access without disturbing another passenger — a meaningful feature on overnight intercontinental sectors. Each seat also converts to a fully flat bed.
Aim for a window seat in a row near the middle or front of the Economy cabin for the best combination of space, a wall to lean on, and reasonable boarding/deplaning speed. Exit rows bring extra legroom at the cost of a seat-selection fee. Avoid the last few rows by the rear galleys if you plan to sleep.
