There are no direct trains from Heathrow to Farnham. The simplest journey is to use the express RailAir coach service to Woking station. At Woking there are direct trains to Farnham. This avoids a complex journey via central London which would involve multiple changes.
Booking coach tickets
Tickets for the RailAir coach can be booked up to three months in advance through the website
www.railair.com. Tickets for July will be available for booking by the end of March.
The best prices are found by booking in advance, but it is possible to board the coach
without a booking and pay when you board, providing there is enough space. The coach driver will accept cash and contactless payments.
If your flight is delayed, your ticket will still be valid, and you will be able to catch a later service than the one you booked as long as there is enough space on board.
Tickets includes two 30kg bags, plus hand luggage, per person. If you need to bring extra luggage you can pay a £5 supplement per bag.
