Flight from Washington, D.C. to London Gatwick Airport

DeeFlew with United Airlines-Feb 2025

For me the best route to LHR is the late night departure on UAL. The flight is often roughly 6.5 hours so I skip dinner, use an eye mask and earplugs and try to sleep.

EllenFlew with British Airways-Oct 2024

Do not check your bag if at all possible, especially if you have a connecting flight. Your bag will not make it.

CraigFlew with United Airlines-Jun 2024

Get to beginning of boarding group early. Bring as little on board as possible due to small overhead bin space.
