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

Our return flight was on SAS Business Class. It is well worth the extra money.

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.
VernonFlew with American AirlinesLAX-LHROct 2024
Don’t fly American through British Airways. Business Class not nice enough for the price.
RichardFlew with American AirlinesSAN-LHRAug 2024
BA is pricier in business class compared to Lufthansa but much better. Biggest negative is connecting through Heathrow

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.
Verified travelerFlew with British AirwaysLAX-LHRFeb 2024
I would strongly recommend BA for this route.
AnthonyFlew with American AirlinesLAX-LHRDec 2023
fly Qatar or Singapore airlines if you can

I would say perhaps virgin would be a better alternative
