To hijack this thread... booked YUL-YVR-HNL a while back, and the YVR-HNL flight got pushed back by 10 hours or so, getting into HNL in the evening. That's the only flight of the day, so if I tell Aeroplan it doesn't work for me and I need to be in HNL by (say) noon that day, how likely is it that I'll be able to get them to book me on UA revenue business?
