Cass, unfortunately, as usual, The Local isn't very precise in their "reporting."
Yes, today late morning, the SNCTA union, which has the biggest presence among French air traffic controllers, withdrew its strike notice for tomorrow.
However, that doesn't mean that everything will be back to normal tomorrow.
There are two main reasons for this:
First of all, the smaller unions have not withdrawn their strike notice.
Second, and most importantly, since the strike was already slated to start within 24 hours, the French civil aviation authority had already directed airlines to cancel huge percentages of flights. It is unclear how much elasticity there is in the system that would allow airlines to re-instate flights (with pilots, on-air personnel and ground crews) that they had planned to cancel due to the strike.
Things will be better tomorrow than might have otherwise been, but I don't know by how much.
