I just went on a trip from ORK-LHR-SFO. I checked in 24 hours before the LHR-SFO leg and got both boarding passes, and went off on my ORK-LHR flight. All well and good, except when I went to board in LHR, the machine went beep. For the briefest of seconds, I was hopeful of an op-up, but it turns out I'd been marked as a misconnect, despite having an assigned seat (which I'd paid for) and a boarding pass.

The guy there pressed a few buttons, called someone somewhere and I was free to board. Since I was by now the very last to board, I didn't have time to sit around and talk to him about why this was or what I'd done, and had to run aboard, but can anyone here tell me what could have happened. I would've suspected a cockup in ORK, but I checked in online, so I just don't know.
