Codeshare means other airlines that AC can book you on, with an AC reservation PNR..
So book with AC, flying other metal.. AC has arrangments with these airlines to book passengers on their metal.. i.e. UA/CO
I think there will be quite a few AC flights going.. just less certainty with the strike..
