Refund of reservation only online booking
 

Is it possible to obtain a refund on an online booking containing seat reservations only? (The passenger concerned is entitled to free travel but cannot now make the journey due to attending a funeral elsewhere)

You can apply, the 80% rule should apply.

You need to change this link which no longer works:

You purchased a ticket online

To be eligible for a refund of a ticket purchased online you must cancel before departure time, full details can be found here
