Changing seat reservations LNER

[mrbouffant]

Via the Southern Railway website I bought advanced singles for myself and my 17 year old son to go from Kings Cross to Leeds and back on 9th September.
Because he has a 16-17 saver, I had to add two journeys to the basket, one with a railcard and one without. On checkout, the system allocated us seat reservations in different carriages for both the outward and return journeys!
Is there a way I can contact LNER to change these so we may sit together?
Thanks.

You won't be able to change them, but you can use the LNER website or app to book two new ones at zero cost and ignore the ones you got with the tickets.

Ah excellent. That was easier than expected. Thanks!
