Similar happened to me in ORD. AA canceled a ORD-BOS segment and a subsequent DCA-MIA-LHR claiming that QF had done some kind of mix-up when I asked them to change dates/times in MEL one month before. BA said everything was OK, but AA refused to check me in. Luckily I managed to fly ORD-YYZ-BOS on the same date as originally planned...
