Philippine Airlines is upgrading its service between Heathrow and Manila this winter.
The airline will deploy a three-class Airbus A350-900 on the route in place of a Boeing 777 from October 28.
The move will see the airline introduce a premium economy cabin for the first time on a route to Europe.
The new generation Airbus twinjet has a long-range capability of up to 8,000 nautical miles and a quieter cabin with up to four times less noise.
The premium economy has 24 seats on a 2-4-2 configuration. It features a seat pitch of 38 inches and width of 19 inches.
The introduction of premium economy on the London route means passengers can connect to destinations including Auckland, Melbourne and Hong Kong with the airline in the mid-range cabin.
The business class cabin has 30 seats in a 1-2-1 configuration with a seat pitch of 44 inches and width of 23-24 inches.
The 241 economy seats un a 3-3-3 configuration have a pitch of 33 inches and width of 18 inches. Features include a four-way headrest and USB power ports.
All seats on the A350 have personal TV screens with dual screen functionality. Passengers can pair screens with their mobile devices via an app.
High-speed Wi-Fi will be offered free for all passengers, subject to time and volume caps, with “affordable renewal plans”.
