AC changed my outbound flight for next May, they sent me an email and text a few days ago, when I go to check on the website it does not give me the chance to change to alternate flights or dates and is treating it as though I accepted the changes (which I did not do). Should I call AC ASAP to resolve (I am travelling now) or can it wait until I get home on Friday or later given the extra long wait times with the pending strike/lock-out?
