Changing only one leg of a UA MP itinerary operated by AC
I booked an Air Canada award ticket using United miles.
I need to change my final destination of my award ticket. I can't make the destination change since it needs to be reticketed and there is no availability to reticket the itinerary.
If I cancel my award ticket, does my current award return to inventory or not? If it does return to inventory, how quick is it? I hope this makes sense.
