AF codeshare checkin vs strike waver
 

I am on a DL W fare upgraded with miles. I am ticketed on AF CPH-CDG-MSP-OKC tomorrow (6/29/16).

In the past I have simply gone to the AF or KLM web on these codeshares to check-in since that is the only way to get a seat assignment like PE for xxx-CDG.

However, today I have been waiting because there is a National Air Controllers strike in France and I want to know if it will extend to tomorrow.

The question then is if I check-in with AF can DL check me out later and move me to another flight if the strike continues and is acknowledged on the AF web?
