Flight from New York John F Kennedy Airport to London Heathrow Airport

Verified travelerFlew with British AirwaysPHL-LHRSept 2024

The over night flight was good. We were given a delicious dinner and then were able to take some time to slowly drift off to sleep, if possible. The choice of movies was really great too!

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.

Would fly this route with this airline again.

SuzanneFlew with British AirwaysPIT-LHRMay 2024

- Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.
