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

Large number of passengers on the flight so arrive early to the airport and to the boarding gate

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

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.

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.
