In response to what is says is ‘strong forward bookings’, the airline is operating the 777-200 aircraft-served route year-round.
The morning departure out of Heathrow complements the existing afternoon flight to the Arizona capital which is operated by transatlantic joint business partner, British Airways.
Rhett Workman, American’s Managing Director of Heathrow, says: “Our transatlantic partnership with British Airways, now in its ninth year, continues to strengthen.
“Adding a second daily London to Phoenix flight and increasing it to a year-round service, is the latest example of the opportunities created when two strong, world-class airlines come together.”
Features of the 777-200’s Flagship Business cabin include lie-flat, aisle-accessible suites with premium noise-cancelling headphones and celebrity chef-inspired menus.
Key Premium Economy draws include a leather seat with 38-inch pitch, noise-reducing headphones, an enhanced food and beverage service and a personal amenity kit.
Complimentary meals, beer and wine, inflight entertainment and high-speed wifi is available in all cabins.
Phoenix is American’s ninth US destination from Heathrow and brings the airline’s peak daily departures to 21.
This summer, the airline is also introducing a further eight new flights between Europe and the US, all operated as part of the Atlantic Joint Business with British Airways, Iberia and Finnair.
These include a summer seasonal service between Edinburgh and Philadelphia and a daily summer seasonal service between Dallas/ Fort Worth and Dublin. “
