Booking flights can be unpredictable, british airways customer service came through for me when I ran into a booking issue. I had already selected my seat, but for some reason, it got reassigned without notice. Noticed it just before check-in and had to sort it out. The first agent wasn’t much help, but after some persistence, I got someone who actually fixed the issue. Ended up with an even better seat, but the stress of last-minute changes wasn’t ideal. Keeping an eye on seat assignments earlier next time!
