How to book cheap train tickets from Heathrow Terminal 3 to Southampton

Travelling in off-peak train times

Off-Peak train tickets are generally cheaper than peak-time tickets, allowing travel outside morning (06:30-09:30) and evening (16:00-19:00) rush hours on weekdays. If your schedule allows for flexibility, choosing off-peak times for your trip from Heathrow Terminal 3 to Southampton can result in significant cost savings.

Using the Railcard for 1/3 off

You can choose a Railcard to help you save up to 1/3 on fares from Heathrow Terminal 3 to Southampton for various reasons, such as your age (including the 16-25 Railcard or Senior Railcard) or options geared towards group travel (Family & Friends Railcard and Two Together Railcard).

Split Tickets to save an average extra 30%

Splitting tickets is a perfectly legal practice that involves purchasing separate, cheaper tickets for different segments of your journey on the same train instead of a single ticket for the entire trip. For example, if you are travelling from Heathrow Terminal 3 to Southampton, you might discover that buying a ticket from A to C, and then another ticket from C to B, is more economical than a direct ticket.

Book in advance to save an average of 61%
