At three months in advance, it is perhaps not guaranteed that the train won't lose it's reservations, as has happened to me and others.If I've booked seat 3 months in advance and someone is sitting in my seat there will be, shall I say, a robust discussion.
If it's shown as available then any such discussion needs to be with the crew to find you an alternative.
Equally if it's shown as reserved but someone else is occupying the seat and also has an identical reservation, again it's for the crew to find you an alternative.
If no alternative is available, LNER will give you compensation under their Seat Guarantee scheme.
If no standard seats are available and first class seats are available, it's possible the crew may use their discretion to upgrade you.
I would suggest that any discussion isn't too robust, at least not to begin with; asking nicely may yield a better outcome.
Agreed.If there were no reservations showing, then they don't apply (as stated by the byelaw) and you would be in the wrong - doesn't matter how long in advance you booked it.
If this occurs your argument is with the TOC, not whoever happens to be sitting in the seat.
