I have just heard that my Sunday afternoon LNER Edinburgh to London has been the cancelled. The email says to get the earlier or later service. I intend to get the earlier service. I have a Seatfrog first class upgrade for my original booking. Is there anyway I can still travel first class? I imagine my new train will be very busy so being in first class would make things more comfortable. If no first class can I get a reservation on my new train? I can go into Edinburgh station in the morning, so any special suggestions on what I should be asking? Thank you.
