Insights shared by verified travellers who flew the route from London to San Francisco 
Verified travelerFlew with American AirlinesLHR-SFOMar 2024
Heathrow is vast, allow plenty of time to drop bags and go through security. At San Francisco the immigration takes a bit of time and we had to wait around 1.5hrs, bare this in mind when booking car rental. The is a shuttle train from the airport to the car rental area which is very slick and efficient.
Ana-MariaFlew with IberiaLHR-SFOMar 2024
In London triple check your flight they have multiple leaving for the same destination once - it is easy to get them confused
