Flight from London Stansted Airport to San Francisco

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

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.

In London triple check your flight they have multiple leaving for the same destination once - it is easy to get them confused
