Interesting to see this. Had no idea they were using the same flight number for the turnaround. Looks like this is pretty standard on certain routes, now that I have some idea of where to look. So I guess the big question is if they are marketing these as direct flights from XXX to XXX with a stop in YYY or if they're just recycling the flight number. I can't imagine the system would let you book them as a direct flight on a single PNR, but you can book them as back-to-back segments on a single PNR. Should be fine for posting, since the system knows the direction. Agree about hanging on to BPs until things post, however.
