I can't find the answer to this. I have 2 award tickets booked and just found out person I am travelling with can't go. When would be the best time to cancel them. I just checked and there isn't any MileSaver availability on the route for the days I am travelling so I am leery about cancelling and trying to rebook. Will AA just cancel the one ticket and leave mine or should I just wait and cancel their ticket the day of departure?

Thanks
