With its tricolor tails, British Airways is one of the most easily-recognizable airlines on the world stage. While the carrier's first class cabins aren't universal, the UK flag carrier's widebodies all feature a business class product known as Club World. The size of these cabins varies between aircraft types, as we shall now explore.

1 Airbus A380

As you might expect, British Airways' largest Club World cabins can be found onboard its Airbus A380s, which, since the retirement of its Boeing 747-400s, are now the airline's only widebody quadjets. According to ch-aviation.com, Club World accounts for 97 of the aircraft's 469 seats, which equates to 21%.

On the bottom deck, these lie-flat beds are laid out eight abreast near the wings in a 2-4-2 configuration, alternating between forward and rearward-facing seats. Meanwhile, upstairs, Club World is situated in the front and central portions of the fuselage. Here, its layout is a narrower 2-3-2 to account for the roof's curvature.

2 Boeing 777-300ER

The Boeing 777-300ER is a rather different aircraft from the Airbus A380 in certain respects, as it has just one passenger deck and two engines, and it was built on the other side of the North Atlantic Ocean. However, in British Airways' fleet, it is the closest aircraft to the A380 in terms of Club World capacity, with 76 seats.

According to aeroLOPA, these are situated behind an eight-seat first class cabin, stretching all the way back to the rear of the jet's wings. Unlike the Airbus A380, every seat has direct aisle access, as they are laid out four abreast in a 1-2-1 configuration. BA also has a second 777-300ER layout with 56 Club World seats.

3 Airbus A350-1000

Moving back to Airbus, British Airways' next-largest Club World cabins can be found onboard its A350-1000 jets. These next-generation European widebodies have 56 Club World seats onboard, which fold down into fully lie-flat beds.

Unlike the Airbus A380 and the Boeing 777-300ER, the UK flag carrier's A350-1000s don't have a first class cabin. As such, the aircraft's Club Suites stretch from the front of the passenger deck back to the leading edge of its wings. Laid out in a 1-2-1 setup, the outer seats face the windows, and the central seats face inwards.

4 Boeing 777-200ER

British Airways' fourth-largest aircraft type in terms of the size of its Club World cabins is the Boeing 777-200ER. While data from aeroLOPA shows that the UK flag carrier has five different configurations for this aircraft type, the most sizeable Club World cabin can be found onboard particular examples with 49 Club Suites.

These are laid out in the standard four-abreast 1-2-1 configuration, stretching from just behind the eight-seat first class cabin to the center of the aircraft's wings. However, with 12 rows of four seats only adding up to make 48, there is one extra seat (8K) in a row of its own at the rear of the first Club World section.

5 Boeing 787-10

Other 777-200ERs have a 48-seat Club World cabin, which is also the largest offering on British Airways' Boeing 787-10 Dreamliner aircraft. These have an almost identical configuration to the aforementioned 49-seat setup onboard certain 777-200ER jets but with one seat fewer; there is no odd one-seat row present.
