The KLM Royal Dutch Airlines Boeing 737-900 carries 192 passengers across Business + Economy. Power is available on this aircraft. Seats are 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 1C, 1D, 15A, 15B, 15C, 15D. Another 48 seats are rated best or good. Look for exit rows 15 and 16 for extra legroom. The map marks 12 seats with extra legroom.
Seats rated avoid on this map are 10A, 14A, 14B, 14E, 14F, 31A. Another 17 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
The 737-900 carries more Business seats than the -700 or -800 versions, which reflects KLM's deployment of the larger aircraft on routes with stronger premium demand. The seat product is similar across the variants — blocked middle, recliner — but the larger cabin feels less intimate.
The 737-900's extended fuselage means a larger Economy cabin sharing the same number of rear lavatories as shorter variants. On full flights and during peak periods, queues can form, which is an additional reason to prefer forward Economy rows.
For passengers prone to motion sickness or sensitive to turbulence, the over-wing rows are the most stable position in the cabin. The practical trade-off is that you're mid-cabin — not near the front exits or exit-row legroom, but a reasonable compromise.
