Air TransportUnited Airlines has converted a significant portion of its Boeing 787-9 orders to the higher-capacity 787-10, according to information reported by The Air Current.
The change involves 56 aircraft originally ordered as 787-9s, which will now be delivered as 787-10s starting in 2028. Prior to the conversion, United’s outstanding Dreamliner orders consisted entirely of the 787-9 variant, with no additional 787-10s planned beyond those already in service.
United operates an all-Boeing widebody fleet made up of the 767, 777 and 787 families. The Boeing 767 is expected to be the first type to exit the fleet, while the 777 is projected to remain in service for at least another decade. As a result, the 787 has become the backbone of the airline’s long-term widebody renewal.
The airline currently operates 80 Boeing 787s across all three variants: 12 787-8s, 47 787-9s and 21 787-10s. Before the latest adjustment, United had 141 additional Dreamliners on order.

The 787-9 remains central to United’s ultra-long-haul network, which includes some of the longest routes operated by any U.S. carrier. These missions require maximum range and high fuel efficiency over extended distances, roles for which the 787-9 is well suited.
The 787-10, while offering less range, can cover the entirety of United’s European network, all South American routes and several destinations in North Asia. For these markets, the aircraft offers a substantial increase in capacity with only a marginal increase in operating cost compared with the 787-9.
The higher seat count allows United to improve unit costs without adding frequencies, while still supporting premium-heavy cabin layouts. The airline has already applied this strategy on some of its newest 787-9s, which feature relatively low total seat counts with an emphasis on business class and premium economy.
The expanded 787-10 fleet is expected to play a key role in replacing Boeing 767s on transatlantic services, including routes to major European hubs such as Frankfurt and London Heathrow, which fall well within the aircraft’s performance envelope.
