Mrs Y and I booked to visit family over Christmas and this week have managed no less than three e-mails indicating itinerary changes. The upshot was that our 16:30 departure for home was nixed and we were booked on an earlier flight at 11:50. Which would mean a 7:30 hour wait in Toronto. Much though I like the domestic MLL in YYZ, seven and a half hours is a bit much. So, I called AC and discovered that there was no way to get rebooked on our original flight and no other itinerary was going to work. The only reasonable fix left was to rebook the final leg so we get home hours earlier. Which is ok, as it leaves us in YYZ for only an hour. But the end result is that we can't do lunch with family on the day we return, as we had originally planned. During the conversation with the agent he mentioned two or three times that I should call customer service because all he could do was rebook my flights. It seems he was inviting me to seek something more than a rebooking to compensate for the inconvenience. Which leads to my question: assuming I pursue this any further, what is reasonable to request? Upgrade on final leg? Upgrade both ways? More, less, anything, nothing? All advice gratefully received.
