Flight from London Gatwick Airport to San Francisco

AlastairFlew with British AirwaysLHR-SFOFeb 2025

Make sure your free checked luggage is for outward and return flights.

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
