If you're on the Sunday night flight ex LGW this originates from MAN.As LGW are checking in at the same time as MAN, Aviance at MAN decides who sits where i.e. allocate a block of rows for LGW depending on how many is booked for the flight.
Let me know nearer the time, if this is the flight you're on and I'll see what I can do.
Think it's the MON6414.
