How to book cheap train tickets from Cardiff to Heathrow Rail

Travelling in off-peak train times

We recommend buying train tickets from Cardiff to Heathrow Rail during off-peak hours. These times are usually before 06:30, between 09:30 and 16:00, and after 19:00 on weekdays, as well as all day on weekends and bank holidays.

Using the Railcard for 1/3 off

You can choose a Railcard to help you save up to 1/3 on fares from Cardiff to Heathrow Rail 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). Discover more here.

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.

Book in advance to save an average of 61%
