The short answer, and the caveat that matters
On British Airways' legacy Boeing 787-9 and 787-8 cabins, seats 41A and 41K are window seats with no window. There is cabin wall where the opening should be. If you pick 41A expecting a view on a long flight, you get a blank panel for the whole journey.
The caveat is the part most seat advice leaves out: that seat number is only the right one to avoid on some of the fleet. British Airways has been retrofitting its 787-9s with Club Suite, and the retrofit renumbers the cabin. On a Club Suite aircraft the windowless pair is 71A and 71K, not 41A. On the 787-10, economy runs to row 48 and row 41 is an ordinary window seat with a window in it.
So the useful question at the seat-selection screen is not "is 41A bad" but "which cabin am I looking at".
How to tell which aircraft you have
You do not need to know the registration. The row numbers give it away:
- economy rows numbered from 30 to 44 — legacy 787-9 or 787-8; the seats to avoid are 41A and 41K, and rows 42 to 44
- economy rows numbered from 60 to 75 — Club Suite retrofit; the seats to avoid are 71A and 71K, and row 73 onwards
- economy rows numbered from 30 to 48 — 787-10; row 41 is fine, the rows to think twice about are 47 and 48
The pattern is consistent because the problem is physical, not editorial: the windowless positions sit at the same place in the fuselage on the 787-9 whichever way the rows are numbered, and the 787-10's longer economy cabin moves the rear boundary further back.
What is actually wrong with 41A
Three things stack up, and only the first is unique to it.
No window. The seat is against the wall in a position where the cabin has no window opening. Electronic dimming, the 787's signature feature, is irrelevant here: there is nothing to dim. On a daytime flight the neighbouring passenger controls the only view in the row, and on a night flight you lose the orientation that a window gives when you wake up.
The lavatory cluster behind you. On the legacy layout, rows 42, 43 and 44 are the rear lavatory zone. Sitting in 41A puts you immediately ahead of it, which means foot traffic in the aisle beside you for most of the flight, queueing passengers standing at your shoulder, and the door cycle sound at close range.
Deplaning and service order. The back of the cabin is served last on most passes and leaves the aircraft last. That is a minor annoyance on a short hop and a real one at the end of a long-haul flight when a connection is tight.
None of this makes 41A unsafe or unusable. It makes it the seat you would not choose if the map had shown you what you were choosing, which is the whole point of checking.
On the Kuala Lumpur route specifically
British Airways flies London Heathrow to Kuala Lumpur daily, and the aircraft is the 787-9. The route returned to the network in April 2025 and has continued through 2026. The airline uses a 216-seat 787-9 on the route, with a 215-seat Club Suite variant appearing occasionally, and the aircraft carries four cabins: World Traveller, World Traveller Plus, Club World and First.
That mix is why the advice has to be conditional. Two passengers on the same flight number a week apart can be looking at two different seat maps, and the one who memorised "avoid 41A" will pick 71A on the retrofit and end up in exactly the seat they were trying to avoid.
Because the aircraft type is fixed for the route but the interior is not, check the seat map at the moment of selection rather than relying on what you noted last time. Airlines also swap aircraft at short notice; a seat chosen a month out can become a different seat on the day.
The two cabins, seat by seat
The 216 and 215 figures are not rounding. They are two published configurations of the same aircraft type, and the difference tells you which one you are on before you ever see a row number:
- pre-refit: 8 First, 42 Business, 39 World Traveller Plus, 127 World Traveller — 216 seats
- refitted: 8 First, 38 Business, 39 World Traveller Plus, 130 World Traveller — 215 seats
The refit removes four business seats and adds three in economy. So if the map shows 42 business seats you are on the legacy cabin and 41A is the seat to avoid; if it shows 38, you are on the Club Suite aircraft and the equivalent is 71A. Economy is 3-3-3 either way, with individual screens, electronic window dimming and Recaro seats.
One further scheduling note, because it changes who is sitting around you rather than where you sit. British Airways is extending the Kuala Lumpur service onward to Melbourne from 9 January 2027, with the first Kuala Lumpur to Melbourne departure on 10 January and the first return on 11 January. There is no extra capacity between London and Kuala Lumpur: the same daily flight simply continues. From that date the London leg will carry through passengers to Australia as well as those ending their trip in Malaysia, which in practice means a fuller cabin and less chance of an empty middle seat beside 41A.
The airline has also said that a refitted aircraft is not guaranteed on the route from launch, and that the older 2-3-2 Club World layout may still appear on some flights. Treat the configuration as something to check per booking, not per route.
What to choose instead
If a window matters to you, take a window seat in the middle third of the economy cabin: far enough back from the forward lavatories and galley, far enough forward of the rear cluster. On the legacy 787-9 that means the mid-30s rows rather than the low 40s.
If legroom matters more than the view, the exit row is the trade to consider — but note that on this cabin the row at the front of economy has lavatories immediately ahead of the centre seats, which is its own kind of traffic. A window seat in that row keeps the legroom and puts the aisle between you and the queue.
If you are travelling as a pair, the A and B combination in a 3-3-3 cabin gives you a window and no through traffic at the cost of climbing over one person. For a family of three, the full A-B-C block on one side removes the negotiation entirely.
And if you end up in 41A anyway — a paid seat assignment gone wrong, an aircraft swap, a full flight — the practical mitigations are a window seat's usual ones minus the window: an eye mask rather than the blind, a preference for the aisle side of your own footwell, and low expectations about being served first.
The three cabins side by side
| Aircraft | Economy rows | Windowless seats | Rear lavatory zone |
|---|---|---|---|
| 787-9 legacy | 30 to 44 | 41A and 41K | Rows 42 to 44 |
| 787-9 with Club Suite | 60 to 75 | 71A and 71K | Row 73 onwards |
| 787-10 | 30 to 48 | Row 41 is a normal window seat | Rows 47 and 48 |
The takeaway
Seat 41A on a British Airways 787 is worth avoiding on the legacy 787-9 and 787-8 cabins, where it is a window seat without a window and sits against the rear lavatory block. It is not worth avoiding on the 787-10, where the row is unremarkable, and the equivalent seat on a Club Suite aircraft has a different number. Read the row numbering before you read the advice, and the seat map will tell you which of the three you are dealing with in a couple of seconds.
