United Airlines to launch London Heathrow to Boston flights

United Airlines is launching a new non-stop service between London Heathrow and Boston Logan International Airport.
This is a bit of a surprise, because I assumed United already operated on the route.
It is also, of course, one of the routes that JetBlue intends to launch this year, albeit not to Heathrow. United may simply be doing its best to spoil JetBlue’s launch.

United intends to operate the premium heavy Boeing 767-300ER on the route. This has 46 Polaris business class seats and 22 premium economy seats.
Whilst we have yet to try out Polaris on a real flight (Covid-19 saw to that!) we did get a preview during a grounded press event in 2019.
The flight times are currently scheduled as:
- Departing Heathrow at 5pm and arriving in Boston at 7.30pm
- Departing Boston at 10pm and arriving in Heathrow at 9.35am the next day.
The Heathrow departure is unusually late for a transatlantic flight – most leave in the morning for a mid afternoon arrival in the United States.
Tickets will go on sale in the coming weeks. The exact launch date is still to be confirmed.

How to earn Star Alliance miles from UK credit cards (April 2025)
None of the Star Alliance airlines currently have a UK credit card.
There is, however, still a way to earn Star Alliance miles from a UK credit card.
The route is via Marriott Bonvoy. Marriott Bonvoy hotel loyalty points convert to over 40 airlines at the rate of 3:1.
The best way to earn Marriott Bonvoy points is via the official Marriott Bonvoy American Express card. It comes with 20,000 points for signing up and 2 points for every £1 you spend. At 2 Bonvoy points per £1, you are earning (at 3:1) 0.66 airline miles per £1 spent on the card.
There is a preferential conversion rate to United Airlines – which is a Star Alliance member – of 2 : 1 if you convert 60,000 Bonvoy points at once.
The Star Alliance members which are Marriott Bonvoy transfer partners are: Aegean, Air Canada, Air China, Air New Zealand, ANA, Asiana Airlines, Avianca, Copa Airlines, Singapore Airlines, TAP Air Portugal, Thai Airways, Turkish Airlines and United Airlines.
