Flight from San Francisco to London Heathrow Airport

GeraldFlew with Virgin AtlanticSFO-LHRJun 2025

Virgin Atlantic uses terminal 3. Much faster clearing customs than terminal 5

Eat at the lounge first so you are not stuck eating overcooked cheese ravioli

Verified travelerFlew with IberiaLAX-LHRJan 2025

Make sure you arrive early. Sometimes, the traffic getting to LAX can be a total nightmare.

WeiFlew with British AirwaysLAX-LHRSept 2024

Connection takes long, Make sure you plan enough time.

TapanFlew with British AirwaysSFO-LHROct 2024

Great baggage policy in BA.. The worst part was experience at London Heathrow airport. Security was slow, too many people. Almost lost connecting flight even with 2 hours layover.

Verified travelerFlew with British AirwaysLAX-LHRMar 2024

Pack your own food if you have dietary restrictions and fly other airlines if possible

MichelleFlew with British AirwaysLAX-LHRMay 2024

Make sure you separate your luggage tags from your tickets

ShaunaFlew with British AirwaysLAX-LHRDec 2023

I would suggest calling the airline to make sure that their TV screens work on the back of the seats, and if they don’t work that the entertainment option would work on your cell phones.
