This is a basic question, but I’d rather be sure that I have it straight in my head so if anyone is willing to chime in
please do…

I am flying YQR-YYZ-CLE tomorrow on a round trip ticket with a return on Monday. It’s possible now that I will need to go to YUL on Monday due to a family emergency that is fluid at the moment. I assume that once I’ve flown the outbound I can cancel the return on AC for a full refund/credit due to the potential strike? I think the answer is ‘yes’. I would be flying on DL or AA to YUL so would not be rebooking onto AC.

I have been reading this thread closely over the last few days, but for a few reasons my brain is a muddle at the moment and I want to be sure that I fully understand what my options are.

Thanks!
