jno - // it's been a few years now, but I was sitting in an aisle seat, with a guy next to me. He started talking across me to the woman across the aisle from me. I twigged that they were married but for some reason BA had chosen to put me, and an aisle, between them. I offered to change seats with the woman so they could spend the flight together( which they accepted). But what were BA thinking? //
They weren't 'thinking' at all - seating plans are done by computer bots, when one section is full they move onto the next one, and they don't bother to take into account if people are traveling together because it needlessly complicates things. If people want to sit together, they sort it, as your couple did, and as my wife and I have also done on a number of occasions.
