British Airways has 12 787-10s in its fleet and another 38 on order. These aircraft are larger than the other two variants of Dreamliner, which are also in the British Airways fleet, but have a shorter range. Still, they are capable of impressively long routes, with a particular focus on the transatlantic. Flying out of Heathrow, British Airways uses its 787-10s for multiple routes over 4,000 miles, with destinations including Portland, Dallas, and Vancouver.

You can discover the longest routes British Airways 787-10s will fly in 2026 from the analysis of data acquired from Cirium below. The article then explores British Airways’ 787-10s and how the carrier uses them differently from the other smaller variants of Dreamliner in its fleet. The carrier’s 787-10 is noteworthy for its superb products available for premium passengers, including first class and Club Suites.

The Longest 787-10 Routes

Simple Flying obtained data from Cirium on all 787-10 routes scheduled by British Airways for 2026 that are longer than 3,260 miles. It shows a large number of routes over this distance, some approaching 5,000 miles. The longest is to Portland, a 4,914-mile journey. Some of these long routes have an incredibly high frequency. Seattle-Tacoma International Airport will be served 376 times in 2026, amassing over 460 million available seat miles. Chicago is unsurprisingly the city with the most British Airways 787-10 flights in 2026, with 500 flights planned. This route averages 3,963 miles. Towards the bottom is the still noteworthy 3,420-mile flight to Dubai International Airport. British Airways plans to operate this route 454 times in 2026, offering 116,000 seats and almost 400 million available seat-miles.

The table below details the top five longest. Please note that only the outbound leg from London Heathrow is included, and each route has an equivalent return leg.

The 787-10 aircraft have eight first-class seats and a great number of business class seats. These jets also have a larger economy class cabin than the other 787 variants flown by British Airways, but a notably smaller premium economy cabin. The carrier uses these aircraft to fly to some of its most popular destinations in the US, including Boston, New York-JFK, and Chicago O’Hare. Outside the US, popular destinations served by these jets include Dubai and Doha.

The Purpose Of The 787-10 For British Airways’ Fleet

Finding success flying the Boeing 787-10 is all about seeing the opportunity within a strange middle-ground. This aircraft pushes the boundaries of mid-size, larger than either the 787-9 or 787-8. Yet, it doesn’t have the capacity or range of the larger widebodies, including the Boeing 777 and Airbus A350. This gap will widen once the Boeing 777X enters commercial operations.

The table below shows the specifications for the Boeing 787-10 compared with the 787-10. It utilizes Boeing’s data and shows that, although there are many shared characteristics, there are notable differences in range, capacity, and length:

Where the Dreamliner thrives is its lower operating costs than other mid-size aircraft, while still giving carriers the flexibility that comes with mid-size jets. The 787-10 lacks the ultra-long-range capabilities of the Boeing 787-9 and is the lowest-selling Dreamliner variant. Yet, it is perfect for slightly thicker and shorter long-haul routes.

The Heathrow To Portland Dreamliner Story

The longest 787-10 flight conducted by British Airways this year will be from Heathrow to Portland. However, this route wasn’t always flown by the 787-10. Instead, when it launched in June 2022 following two years of pandemic-caused delay, the route was flown by the 787-8. Adding Portland and Pittsburgh to the network that day meant British Airways grew its representation in the USA to 26 US destinations.

When originally launched, the schedule included two aircraft. The table below shows the schedule initially operated by British Airways:

Despite the pandemic causing unwanted delays, British Airways timed its entrance into the Portland market perfectly. Delta Air Lines had closed its seasonal summer Portland-Heathrow service in September 2019 after launching it in May 2017. Delta carried 110,464 round-trip passengers, for an average seat load factor (SLF) of 78.6%. During the summer peak of 2019, Delta was operating this route once daily. Delta halting these services meant that when aviation suddenly started again, there was an enormous capacity gap to fill on the Heathrow to Portland route.

Inside The British Airways 787-10

British Airways’ stretched 787-10s are among the youngest aircraft in its fleet. Only the carrier’s Airbus A350-1000s have a lower average age. The carrier flies this aircraft with a four-class configuration, featuring first class, even though such top-end flying has taken a step back. The cabin has 165 seats in economy (World Traveller), 35 in World Traveller Plus (premium economy), 46 in Club World (business), and eight in first class. Club Suite and First both make use of 79-inch flatbeds in a 1-2-1 configuration. This means every seat is comfortable for sleeping and offers direct aisle access. The main perks of first class are exclusivity, seats that are an inch wider, and substantially larger IFE screens.

Behind the first class and Club Suite cabins are the World Traveller Plus seats. These seats are in a 2-3-2 configuration, meaning there is just one middle seat per row. You can enjoy 38 inches of pitch and 18.7 inches of width.

The economy class seats have 31 inches of pitch. These cramped seats are in a 2-3-2 configuration, becoming 2-3-2 for the final three rows, where the aircraft begins to narrow.

First Class Is Available On British Airways 787-10

Premium passengers love flying aboard 787-10s as they still offer First Class. Although British Airways business class is a strong product, the 787-10’s first class offers tangible benefits beyond the additional inch of width mentioned earlier. These benefits begin on the ground, where first-class passengers can enjoy access to First Wing security and the ConcordeRoom. Such products can make your flying experience even more seamless than in business class. The landside-to-airside transition can take as little as 6 minutes.

Exclusivity and great service continue in the skies. As there are only eight first-class seats onboard, there is a higher crew-to-passenger ratio than on any other class. That gives you access to the dine-on-demand service.

Yet, British Airways is not trying to emulate the decadent luxury offered by Middle Eastern or Asian carriers. Instead, the first-class experience aboard 787-10s is built around accessibility and convenience, with a particular focus on transatlantic hops. The carrier is set to double down on first class as part of its ongoing £7 billion ($9 billion) transformation.

Where British Airways Flies Its Other Dreamliner Variants

British Airways has shown far more commitment to the Dreamliner program than just flying its largest variant. In December 2025, British Airways had all of its 42 787s based at its London Heathrow Airport hub. The fleet included 12 787-8s, 18 787-9s, and 12 787-10s. The order sheet shows that, with 38 787-10s on order, this aircraft was destined to have a larger role in British Airways’ fleet. British Airways is also notable for being the only 787 operator within the International Airlines Group (IAG).

The carrier’s 787-8s are flown to low-demand destinations because they have fewer seats and business, premium economy, and economy services on board. The lowest capacity configuration has just 204 seats available: 31 in business class, 37 in premium economy, and 136 in economy. In the first half of 2026, British Airways plans to fly this aircraft on 20 routes across six nations. India accounts for 35% of the flights, and the five most served destinations will be Hyderabad, Chennai, Mumbai, Montreal, and Toronto. Meanwhile, Abu Dhabi is the least served route. The low-capacity aircraft is also set to be used for flights to St. Louis, a new seasonal service starting on April 19.

Meanwhile, British Airways’ Boeing 787-9s have eight first class seats, additional premium economy and business class seats, and fewer economy class seats. That indicates this aircraft is used on routes with strong premium demand. However, these destinations often also have lower overall demand.
