Because of the chaos at Euston today my Avanti journey was delayed by 4 hours which puts me in the full refund of a single or return ticket. But what counts as a return ticket? The tickets I buy (Standard Premium) are only available as two single tickets. So can I claim for both of those or just the delayed journey? And does the return have to be after the delayed journey or can it be before with the delayed journey being the return leg? I’m doing this journey all the time so have a number of tickets purchased in both directions. Thanks.
