All I heard was that her partner could not travel with her and she needed to get back to HKG.They were having none of it at check in. The only reason I know is because I was using the first class check in and the supervisor needed to use that terminal to see what could be done and the women in question was on the next check in to me which was business class. I heard her talking to the FA during the flight and she was just glad to be getting back and so grateful to the flight crew who gave up the pilots sleep seat.
