Flight from Austin to London Heathrow Airport

AndrewFlew with United AirlinesIAH-LHRJul 2025

United really looked after me, just make sure you arrive good and early to ensure an unpressurised check in

Verified travelerFlew with British AirwaysIAH-LHRMay 2025

Heathrow has good signage. There are lots of people going to the same terminal waiting for the train. Be patient and when you have connecting flights choose a 2-hour layover.

Verified travelerFlew with IberiaDFW-LHRMay 2025

Take a pillow you can sleep on and rest.

JamesFlew with American AirlinesIAH-LHRApr 2025

Try to avoid Heathrow! Not the most convenient to get into London unless you have a driver. Also, Heathrow needs better signs on where to go to exit and better wifi for foreign travelers.

Verified travelerFlew with IberiaDFW-LHRDec 2024

If you can't check in online do it by phone, don't do it at the airport because the system sucks!
