How to book cheap train tickets from Heathrow Terminal 4 to Cardiff

Traveling in off-peak train times

Taking advantage of Off-Peak train tickets is another effective way to save on your train journey from Heathrow Terminal 4 to Cardiff.

Get 1/3 off with a Railcard

Split tickets to save an average extra 30%

Splitting tickets involves buying separate, cheaper tickets for different parts of your journey on the same train instead of just one ticket for the entire trip. For instance, if you're traveling from Heathrow Terminal 4 to Cardiff, you might find that purchasing a ticket from A to C, then C to B costs less than a direct ticket. This method is perfectly legal and often doesn't require leaving your seat.

Book in advance to save an average of 61%
