Insights shared by verified travelers who flew the route from California to London 
PallaviFlew with British AirwaysSFO-LHRApr 2025
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.
SueFlew with Alaska AirlinesLAX-LHRSep 2024
Our return flight was on SAS Business Class. It is well worth the extra money.
WeiFlew with British AirwaysLAX-LHRSep 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.
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
Verified travelerFlew with British AirwaysLAX-LHRMar 2024
Pack your own food if you have dietary restrictions and fly other airlines if possible
Verified travelerFlew with American AirlinesSFO-LHRApr 2024
best airlines for business class: KLM and Turkish
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.
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
Verified travelerFlew with British AirwaysLAX-LHRFeb 2024
I would say perhaps virgin would be a better alternative
