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

Verified travelerFlew with American Airlines-Jun 2025

Make sure you do not need the transit visa.

LisaFlew with British Airways-May 2025

Make sure you have enough time in London if you have a transfer flight. I would recommend at least 2 hours.

RadicalFlew with American Airlines-May 2025

Don’t put everything in your gate check bags. Make sure you have clothes in your carry on

Verified travelerFlew with British Airways-Oct 2024

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

GlennFlew with British Airways-Jun 2024

British airways could have many delays, ensure there's enough time for the layover

Verified travelerFlew with British Airways-Mar 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.
