I booked a non-refundable train ticket from London to Paris (return journey) via Trainline just today. Unfortunately later that same day I put my passport through the washing machine, completely obliterating it.
I see on Trainline that while I can't refund the ticket, I can change the dates. Interestingly as part of this, I can upgrade the ticket to business class, which it says is fully refundable.
While clearly not intended on their end, is this method of getting a refund possible?
