DeeFlew with United AirlinesIAD-LHRFeb 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 AirwaysIAD-LHROct 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 AirlinesIAD-LHRJun 2024
Get to beginning of boarding group early. Bring as little on board as possible due to small overhead bin space.
