I have an Advance Single, do I need a seat reservation as well?

All Advance Single tickets already come with a reservation included as standard, so you don't need to make one. Your reservation is visible on your ticket or if you booked via the LNER website or app, through your My account section.

If your ticket doesn't have a coach and seat number, it may mean you have a different ticket type such as Off Peak ticket and you need to reserve a seat.
