Flying EDI-LHR on Thursday and notice that the aircraft is now a long haul 767. I originally had 7K reserved but that seat no longer exists. In MMB I am still showing in 7K but the seat map won’t display so I can’t move myself to a real seat. I tried a dummy booking and the seat map does display but the front 4 rows are all greyed out but there are a few seats available in the WT+ section.

Question: Is it likely that I will be (or already have been) automatically reassigned to the CW section or should I call and grab the WT+ seat now (and perhaps lose the chance of sitting up front?)

I know it is only a short flight but have never tried the LH 767 or the older CW seats and would love to give them a go!
