Hi,

I'm flying this evening to CDG, and managed to get seat 4A on the aircraft (think it's a 321). I checked in this seat but asked to get the BP at the airport.

However, when I go to MMB I see now that my seat has been changed to 5A. The configuration looks the same and so does the aircraft type.
I know that on the BA website is says "BA can change your seat for operational reasons", but is it valid to change the seat of a pax already checked in to accommodate another?

Cheers,
