Have no basis for comparison, but British Airlines does a good job.
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.
NancyFlew with British AirwaysIAD-LHRNov 2024
Looking at schedules and prices, I settled on BA years ago. I have yet to meet an employee who wasn't at the very least pleasant. Most go out of their way in difficult situations to be kind and cheery.
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.
Verified travelerFlew with British AirwaysIAD-LHRSep 2024
Process to get to connecting flights at Heathrow is convoluted/complicated.
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.
SaraFlew with British AirwaysIAD-LHRJul 2024
