Oof, I just saw that AF has now canceled their ABJ-CDG flights for five days straight (Saturday through tomorrow) due to the strike. I'm asking here because I want to be prepared to act quickly if my DL codeshare AF flight on the 25th is also canceled. My booked route is ABJ-CDG-ATL-DCA (with the last two legs on DL metal).

With no good alternatives because it's an AF/SN duopoly here, I'm assuming that means they'll try to reroute me on SN to get me out of West Africa. So would DL then also reroute me to my final destination on SN/UA, or will they reroute me to Brussels and let me take DL the rest of the way to DCA?

Also, if I am put on SN/UA for one or more of the legs, will Delta likely honor a request to credit me for the miles of the route I booked and not the one I end up flying?
