OK, now I have something a little worse to add. Last night (Monday) I went to check-in on-line for my return today (Tuesday) and the system wouldn't let me. Hmmm...

Called in to find out why, and the agent asked if I had really taken the outbound flight, because my return res had been cancelled!! Told her the whole story about the double orange seat and having a seat-sharer show up.

Good thing I called in, so she could recreate my res. 24 hrs ahead of flight time vs. scrambling at the airport. This flight was eventually full, and I probably would not have gotten on had I not called.

I don't see a huge reaction to this thread from the people on here, so maybe it's just not that widespead????
