Flights from Heathrow to Boston: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Heathrow to Boston 
Verified travelerFlew with British Airways-Jul 2026
I still prefer BA for London-Boston but all services, especially food, have been declining over the years. Boston has some of the longest walks in Terminal E. Small carts like they have in many European airports would do a lot to help especially senior passengers.
Verified travelerFlew with British Airways-Apr 2026
Give yourself plenty of time to go through security especially if you have to go from one terminal to the other. 90 mins minimum
Verified travelerFlew with British Airways-Mar 2025
Try to get an aisle seat and walk around the plane as often as possible. Your legs will thank you
ShawnFlew with British Airways-Dec 2024
Know that gates are posted just about an hour before takeoff and it takes a bit of time to actually get to the gate. If you make a mistake there is no train back- you have to walk to the correct area and that are at least 10 minutes apart. Make sure to have ALL liquids ready to place in the tray at TSA
Verified travelerFlew with British Airways-Mar 2024
If you are arriving on a late flight check in to an airport hotel at Logan. Good choice, easy access and good start to your trip
Verified travelerFlew with Finnair-Dec 2023
If you’re looking for a hassle free and good customer experience, avoid BA; Fly American. As soon as you board the plane, set your watch to local US time to help adjust to the time difference.
