Widebody aircraft constitute a massive 44% of 
British Airways’ mainline fleet. According to ch-aviation, it has 131 twin-aisle machines: 43 Boeing 777-200ERs, 18 Airbus A350-1000s, 18 787-9s, 16 777-300ERs, 12 A380s, 12 787-8s, and 12 787-10s.
For years, the 
oneworld member’s 787-8s had one configuration, with 214 seats. Even then, the variant was BA’s lowest-capacity widebody equipment. But some of its 787-8s now also have 204 seats. In a much-delayed process, they have the airline’s new Club Suites with direct aisle access and doors, along with far more premium economy seats.
First, A Summary Of BA’s 204-Seat 787-8s
Ch-aviation indicates that seven of its 12 787-8s have been reconfigured with 204 seats. Meanwhile, an eighth frame, the 12.5-year-old G-ZBJD, is currently in Cardiff, undergoing reconfiguration.
According to Flightradar24, Juliet Delta flew to Wales in February, where it remains. It surely must return to operations soon, as ten months is an extraordinarily long amount of time to be out of action. Clearly, it is doing more than just installing new seats. In November, a ninth frame, registered G-ZBJI, left Heathrow for Cardiff. While unconfirmed, it will presumably also receive the new seats.
The following table summarizes how the layout of BA’s 204-seat 787-8s varies from the original configuration. It has fewer business class seats, with the proportion of them dropping from 16% to 15%. The premium economy cabin has increased substantially, with 48% more seats. With the reduction of bog-standard economy seats, it’ll be a higher-yielding configuration. The fewer seats overall and the smaller business cabin will help dictate where it is flown.

Where BA Wll Fly The 204-Seater: 1st Half Of 2026
The 204-seat 787-8 is now comfortably BA’s lowest-capacity widebody equipment. It is, of course, only flown from 
London Heathrow. According to Cirium data for January to June 2026, 20 routes will see it, based on having at least ten departing flights through the first half of the year.
The 20 routes involve six countries, with India accounting for over a third of all flights (35%). Nearly one in two of BA’s Saudi Arabian services will be on it (46%). In descending order, the five most-served routes are Hyderabad, Chennai, Mumbai, Montreal, and Toronto. With just 20 departures through the first half, Abu Dhabi is the least-served route.
BA will use the low-capacity configuration to St. Louis, which is a brand-new route in its network. Starting on April 19, the seasonal offering will be nearly entirely served by the 204-seat 787-8. The sole exceptions are on April 19 and April 28, when the first-class-equipped, 216-seat 787-9 will be used instead.

It was last flown there in 2022.
It Is Only Heathrow’s 4th Lowest-Capacity Widebody
Sticking to the same January-June period indicates that BA’s 204-seat 787-8s will be only the airport’s fourth lowest-capacity twin-aisle equipment. Azerbaijan Airlines has scheduled its 198-seat 767-300ER to Heathrow on February 24 and March 10, replacing the usual 210-seat 787-8.
Japan Airlines deploys the 186-seat 787-8 on one of its two daily services from Tokyo Haneda. It is used on the less popular overnight service to Europe, with the A350-1000 flown on the other, long-standing operation. In January, the 186-seater departs from the Japanese capital at 1:00 am and arrives in the UK at 6:25 am local time. The aircraft then leaves at 8:25 am and gets back to Asia at 7:25 am+1.
Finally, and most notably, United Airlines’ low-capacity, high-premium, 167-seat 767-300ERs continue to play a major role in that carrier’s operations to the UK’s busiest airport. With a typical ten daily departures, with routes to Newark and Chicago O’Hare, it is used on over half of United’s Heathrow services.
