London Heathrow is an extremely attractive airport for a premium focused airline such as JAL. The airport, has been operating for years near to capacity and is therefore very slot constrained. That means often, if demand can support it, operating the largest aircraft in the fleet is the best thing to do. JAL already does that on one of its two daily services and will soon also on its second.

London Heathrow a Double Daily JAL A350-1000 Service in October 2026
JAL is one of the most premium-focused airlines in the aviation industry. Not only it is also a oneWorld alliance member and has a standing JV with British Airways. All of that makes London Heathrow central to all JAL European operations.
All of that to explain why for the entire 2026 winter season JAL will be deploying two of its largest and most advanced aircraft, the Airbus A350-1000 on the Tokyo Haneda to London Heathrow route.
Starting October 1st 2026 through March 27th 2027 the Japanese carrier will be operating both its daily flights on the A350-1000 upgauging JL41/JL42 from the smaller Boeing 787-9.
The fact we have a start and end date confirms this is a temporary change, for the time being. However, we’ve seen time and time again airlines make changes permanent if results match or exceed expectations.
JL41/JL42 – Switching to the A350-1000 in October 2026
| Flight Number | Departure Airport | Airport Code | Departure Time | Arrival Airport | Airport Code | Arrival Time |
|---|---|---|---|---|---|---|
| JL41 | Tokyo Haneda (HND) | HND | 0015 | London Heathrow | LHR | 06:25 |
| JL42 | London Heathrow | LHR | 09:10 | Tokyo Haneda (HND) | HND | 06:45(+1) |
JL43/JL44 – already operated using the A350-1000
| Flight Number | Departure Airport | Airport Code | Departure Time | Arrival Airport | Airport Code | Arrival Time |
|---|---|---|---|---|---|---|
| JL43 | Tokyo Haneda (HND) | HND | 09:45 | London Heathrow | LHR | 15:55 |
| JL44 | London Heathrow | LHR | 19:20 | Tokyo Haneda (HND) | HND | 17:20(+1) |
The JAL A350-1000 A Premium Heavy Aircraft
JAL is perfectly aligned with its partner British Airways in terms of passengers profile it is looking to attract on the route and aircraft configuration.
Both airlines cater heavily to premium passengers. JAL only seats 239 passengers on its Airbus A350-1000s. That is a remarkably low number.
For context, I recently covered Philippine Airlines (a soon to be oneWorld airline) receiving its first and second A350-1000s and they seat 382 passengers on the same aircraft. That is a full 143 passengers less (in JAL’s case).
| Cabin | JAL Seats | PAL Seats | JAL Layout | PAL Layout |
|---|---|---|---|---|
| First Class | 6 | 0 | 1-1-1 | N/A |
| Business Class | 54 | 42 | 1-2-1 | 1-2-1 |
| Premium Economy | 24 | 24 | 2-4-2 | 2-4-2 |
| Economy Class | 155 | 316 | 3-3-3 | 3-4-3 |
| Total | 239 | 382 | – | – |

PAL= Philippine Airlines
Since its first deliveries in December 2023 the A350-1000 has become the center of JAL’s long haul-high capacity and premium route operations.
It first deployed the aircraft on flagship routes such as Tokyo Haneda to New York JFK. However, as aircraft numbers grew to the current 11 (including the aircraft delivered in late February this year), it started deploying them to other high yield markets such as London Heathrow.
The Ongoing Europe Japan Joint Venture Battle
The increase of seats and capacity JAL will bring to the market in October 2026 can be looked at as part of an ongoing battle to control Japan Europe market between IAG in collaboration with JAL and the Lufthansa Group in collaboration with ANA.
Just 2 days before JAL’s announcement (on June 11th 2026) the Lufthansa Group and ANA announced that ITA Airways would be entering and participating in their Europe-Japan Joint Venture ahead of the upcoming winter season.
Neither group wants to lose market share to the other and, although ITA Airways is not increasing capacity it will be working much closer and contributing much more to the Lufthansa-ANA JV.
If you look at JAL’s move through that lens it can be viewed as a defensive move to protect market share between Japan and Europe.
