Flight from Austin to London Heathrow Airport

PamFlew with American Airlines-Mar 2026

Book premium economy. The extra comfort is worth it.

TaniaFlew with British Airways-Apr 2026

Heathrow airport has become one of the worst airports. Way too massive, like Amsterdam's, way too much walking & navigating. Better have 3 hours for connections and prepare to walk for HALF OF THAT time. LHR was 1 of the best airports 60 yrs ago. Don't expect it to stay same but now its a nightmare. For older folks I suggest using a less massive airport in UK and for American Airlines to do same.

AndrewFlew with United Airlines-Jul 2025

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

Verified travelerFlew with British Airways-May 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 Iberia-May 2025

Take a pillow you can sleep on and rest.

JamesFlew with American Airlines-Apr 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 Iberia-Dec 2024

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