American Airlines is set to launch its overseas intercontinental flight from Phoenix Sky Harbor International Airport (PHX Sky Harbor) to London Heathrow Airport.

The daily direct flight service between Phoenix and London is scheduled to commence operations from 31 March next year and continue through 26 October.

American Airlines will fly a Boeing 777-200ER on the new route. The aircraft will offer 273 seats with three classes of service Business Class, Premium Economy, and Main Cabin service.

British Airways will continue to fly its daily nonstop flight to London Heathrow Airport, departing from PHX Sky Harbor.

With American Airline’s new service, passengers will now have access to 14 flights every week, reflecting the demand for more than one daily flight from Phoenix to London.

“This announcement is yet another sign of how Phoenix is in progressively high-demand for both business and leisure travellers worldwide.”

Phoenix Mayor Thelda Williams said: “Today’s announcement is a reflection of the strength of the Phoenix economy, and one that only promises to make it stronger.

“This has been many years in the making, and I want to thank the oneworld alliance, American Airlines and the City of Phoenix team for working together to turn it into a reality.”

PHX Sky Harbor is working to boost international service, welcoming a Condor Airlines flight to Frankfurt, Germany in May and adding new Montreal service earlier this year.

The airport offers nonstop service to more than 100 domestic destinations and 22 international destinations.

International flights to and from Phoenix already bring in about $3bn per annum while PHX Sky Harbor has an annual economic impact of more than $38bn.

District 4 councilwoman Laura Pastor said: “This announcement is yet another sign of how Phoenix is in progressively high-demand for both business and leisure travellers worldwide and is indicative of our rising position as a major hub.”
