Book premium economy. The extra comfort is worth it.

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.

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

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.

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.

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