Off topic in that it is not BA, but I have a booking for two of us with Cathay for August in economy, four long-haul legs with breaks in between. I was able to reserve seats for all legs.
I got an e-mail yesterday advising me of seat changes – in fact, for just one leg where my wife had been moved to the other side of the aircraft in a different row. I went into the system and, as her original seat was still free, I was able to move her back.
Curious and I cannot work out why. Any suggestions?
