American Airlines is to increase its Heathrow-Miami service this winter.

The airline will fly to Miami twice a week, up from once a week last winter.

It means there will be one flight a day operating Monday to Friday from October to March with its codeshare partner British Airways which flies three times a week.

The new service to American’s Miami hub will offer onward flights to the Caribbean, Mexico and Latin America.

American’s Miami flight will feature fully lie flat Flagship Business seats with Flagship Lounge access in Miami and Arrivals lounge access at Heathrow.

Meanwhile, BA is boosting its daily Heathrow-Philadelphia service by adding three additional flights on Wednesday, Friday and Sunday.

Rhett Workman, managing director of Heathrow for American Airlines said: “This will be American’s biggest year yet at Heathrow with an additional flight to Miami and new year-round service to Phoenix.

“We’re not only giving customers in the UK increased access to the warm winter sun destinations they want, but also working with our partner British Airways to better meet the demand for premium seats in important markets and connecting hubs like Philadelphia”.
