KLM Boeing 737-800 Seat Selection Guide (2026)
KLM operates 35 Boeing 737-800s in a single 186-seat configuration, so there is no version lottery within the type. The whole game is rows 15 and 16. Row 16 is the best row on the aircraft — all six seats have 38" pitch and full recline. Row 15 has the same 38" pitch and looks identical on a booking map, but four of its six seats cannot recline. Avoid 11A and 11F: they have no window at all.
✈️ Quick Verdict
Fleet: 35 aircraft, one configuration — 186 seats, 3-3 throughout
Version lottery: No — but see the WiFi warning below, which is the real KLM short-haul lottery
Best seats: Row 16 (all six) — 38" pitch, full recline
Best aisle pair: 15C and 15D — 38" pitch and they recline, unlike the rest of row 15
Best windows: 23A/23F, 25A/25F, 27A/27F
Avoid: 11A and 11F (no window), rows 31–32 (lavatory), row 30 (lavatory traffic)
The WiFi Trap: KLM's Real Short-Haul Lottery
The 737-800 itself is consistent, but which KLM narrowbody you get is not — and the gap matters more than any seat.
The 737-800 has no WiFi and no in-flight entertainment at all. No seatback screens, no streaming, no connectivity. You get a USB-A socket and a personal device holder built into the seatback, and that is the entire entertainment offering.
KLM's A321neo flies many of the same routes with Viasat Ka-band WiFi. Same airline, same city pair, completely different four hours. If connectivity matters to you, check the aircraft type at booking — not the flight number.
| KLM narrowbody | Seats | WiFi |
|---|---|---|
| 737-800 | 186 | None |
| A321neo | 227 | Viasat Ka-band |
How the Cabin Is Divided
The 737-800 is a single-cabin aircraft in 3-3, rows 1 to 32 with no row 13. Letters are A B C on the left, D E F on the right.
Europe Business is not a separate cabin. As is standard across European short-haul, KLM sells the front rows as Business with the middle seat (B and E) blocked, and moves a curtain forward or aft depending on demand — capped at six rows, or 24 sellable Business seats. When the curtain sits forward of row 7, the rows in front of it that are not sold as Business become Economy Comfort.
The practical consequence: rows 2 to 6 have 33" pitch against 30" for most of the aircraft, whether you buy them as Business, Economy Comfort or plain Economy on a light load. If the curtain is well forward on your flight, row 6 is quietly the best-value seat on the jet.
Pitch Varies More Than You'd Expect
| Rows | Pitch | Notes |
|---|---|---|
| 2–6 | 33" | Business / Economy Comfort zone |
| 7–14 | 30" | Standard |
| 15–16 | 38" | Exit rows — the best legroom on the aircraft |
| 17–32 | 30" | Standard |
Rows 15 and 16 — The One Thing to Get Right
Both exit rows carry 38" pitch. On a seat map they look interchangeable. They are not.
Row 16 is the better row. All six seats are rated good — extra legroom, full recline, nothing behind them to restrict the seatback.
Row 15 has a catch. Because row 16 is an exit row that must stay clear, 15A, 15B, 15E and 15F cannot fully recline. You get the legroom and lose the recline. Only 15C and 15D — the two aisle seats — escape the restriction and recline normally.
The rule: if you want the exit row, take row 16 outright. If row 16 is gone, take 15C or 15D, not 15A or 15F. A window seat in row 15 is the worst of the four exit-row options.
One more knock-on: 14A, 14B, 14E and 14F also have restricted recline, because row 15 is itself an exit row. 14C and 14D recline normally.
The Window Seats That Aren't
Three window positions on the KLM 737-800 disappoint, and one of them badly:
- 11A and 11F — no window at all. Wall only. These book as window seats and deliver a blank panel. The single worst trap on the aircraft.
- 10A — the window is misaligned, set behind the seat. You lean back to see out.
- 17A, 17F, 22A, 22F — poor alignment, though not as severe.
The genuinely good windows are 23A/23F, 25A/25F and 27A/27F — all rated for great alignment, all far from lavatories and galleys.
The Back of the Bus
The last three rows are the worst block on the aircraft and it is worth being specific:
- Row 30 — all six seats flagged for lavatory queuing traffic.
- Row 31 — all six seats have a lavatory door immediately behind.
- Row 32 — same, and 32B through 32E additionally catch galley noise and bright light during meal preparation.
Rows 28 and 29 are clean. If the back of the aircraft is all that is left, stop at 29.

Frequently Asked Questions
Does the KLM 737-800 have WiFi?
No. There is no WiFi and no in-flight entertainment system on any of the 35 aircraft. You get a USB-A socket and a device holder in the seatback. KLM's A321neo, on many of the same routes, does have Viasat WiFi.
Which is better, row 15 or row 16?
Row 16, clearly. Both have 38" pitch, but 15A, 15B, 15E and 15F cannot fully recline because row 16 behind them is an exit row. All six seats in row 16 recline normally.
How many Business seats are there?
It varies by flight. KLM uses a moveable curtain and blocks the middle seat, capped at six rows and 24 sellable seats. On a light load the Business section may be two rows; on a heavy business route it may be six.
Which seats have no window?
11A and 11F — wall only. 10A has a misaligned window set behind the seat. 17A, 17F, 22A and 22F have poor alignment.
Is there a row 13?
No. Rows run 1 to 32 with 13 omitted, so the aircraft has 31 numbered rows.
