The aircraft will replace the current Airbus A350 which flies one of its two daily services.
Starting February 1, Thai Airways’ Boeing 777-300ER aircraft will once again ply the airline’s Bangkok-London Heathrow route. The aircraft is set to replace the Airbus A350 which currently serves one of its two daily services between the cities.
This move reverses the airline’s decision last September to let the newer A350 take over flights TG916/TG917 from the B777-300ER while the carrier’s second daily flight is operated by its A380 superjumbo.
For passengers, the switch back to the B777-300ER will mean an additional 10 seats in business-class, as well as 17 more economy-class seats, compared to the A350.
Other than that, seat layouts and cabin products are essentially the same on each aircraft. Business class seats are configured 1-2-1 in a staggered, forward-facing layout that provides direct aisle access to all passengers, offering 20 inches of width and a fully flat recline.
As for economy class, the setup is 3-3-3 and seats are 18 inches wide.
According to the Thai airline, the reintroduction of the B777-300ER on the route was “due to high customer demand”. That said, passengers who prefer the A350 for its comfort-centric features including advanced air management system, better air pressure control, improved soundproofing, and ambient LED lighting, may be slightly disappointed.
