Make sure you have enough time in London if you have a transfer flight. I would recommend at least 2 hours.
RadicalFlew with American AirlinesPHL-LHRMay 2025
Don’t put everything in your gate check bags. Make sure you have clothes in your carry on

Eat well before boarding if you’re a picky eater.

British airways could have many delays, ensure there's enough time for the layover
Verified travelerFlew with British AirwaysPIT-LHRMar 2024
Go British Air. The nonstop flight is a huge bonus as there are very few such flights to Europe from Pittsburgh. Study the Underground and use it for transportation while there. After you’ve seen the most famous London sights, visit one of the smaller museums, like the John Soames Museum or the Leighton House Museum. Have a drink at the bar on the top floor of the National Portrait Gallery.
