We just had a seat change notification for our award flight to BCN in August - it's now the smallest Club Europe cabin I've seen (two rows), and we were conveniently split across the aisle, but that was easily rectified

More interestingly however, the booking now shows as operated by "BA Mainline Prime Lhr Shorthaul" - I've never seen that before. Has that been going on for a while? Looks a bit like there are so many different BA operations and wet leases around that they are distinguishing more than just the operaiting airline in MMB?
