I joined and bought one ticket but after that I decided not to bother with it; LNER are often found to be charging more than split ticket providers in my experience and a tiny percentage back doesn't offset this
I also want a seat selector that works with all TOCs, not just LNER and I want all my bookings in one place.
I was just looking at a London Kings Cross - Castleford journey on 18/06
19:33 - £29.00
I then stuck in Stevenage - Castleford as I'm actually staying in Stevenage so may not end up in London, 19:55 which is the service above £19.70
...but I then found advances are on offer for the London Kings Cross - Stevenage leg for the service for £4.90, so where have LNER conjured up the extra £4.40 from?!
