I don’t know why BA didn’t just bite the bullet on this, I mean the number of seats in First and therefore, the amount of space. From my experience, and of course I have no other basis to say this, but it seems so often that when I check-in online 12-24 hours before a flight, there are many empty seats in First. Mysteriously, when I board, it’s full. This happens so often and indicates to me that they use it as an overflow for business or complimentary upgrades. I’d love to know what their true revenue generating load factor (if that’s the right term).
