There was no new flight number assigned for my YYZ-LHR flight. It left YYZ at 23.45 instead of 09.10 on the same day. But LHR had 2 arriving the next day with the same flight no. Anyway, my daughter explained that the flight she was trying to find out about was the previous days departure.
My reference to a new flight number referred to a similar delay LHR-YUL a few years ago. That time a new flight number was assigned. Maybe that is what AC should have done this time - but they didn't.
