Insights shared by verified travellers who flew the route from London to Boston 
Verified travelerFlew with British AirwaysLHR-BOSMar 2025
Try to get an aisle seat and walk around the plane as often as possible. Your legs will thank you
ShawnFlew with British AirwaysLHR-BOSDec 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
JaiFlew with British AirwaysLHR-BOSJan 2025
The boarding area was a bit crowded. The restaurants are serviceable, but not great.
Verified travelerFlew with British AirwaysLHR-BOSMar 2024
