Flight from Los Angeles to London Heathrow Airport

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-LHRSept 2024

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

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.

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
