Flight from Boston to London Gatwick Airport

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.
