Flights from Massachusetts to London: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Massachusetts to London 
alyciaFlew with American Airlines-Mar 2026
Long walk between terminals in boston Don't cut connections close
MarilynFlew with British Airways-Feb 2026
Meeting a friend at Heathrow was difficult as there are many terminals so far apart. Access to the train was great and an easy way to get to the downtown area.
Verified travelerFlew with British Airways-Jan 2024
Leave plenty of time if connecting in London as most connecting flights are in a different terminal which requires a bus or tram ride. Also if you’re not at the gate 30 minutes ahead they will not let you on the plane. Apparently this is a Heathrow not airline rule.
