We have been following the AF website closely to see what will happen after the April strike dates. This morning I read that they plan to announce more early May strike dates after failed talks last Thursday with their union.

We are monitoring the AF website twice a day as we are scheduled to fly home from Paris on AF on May 4. We will try to book with a partner airline if our date appears on their list, using similar tactics we had to use on April 10 when we flew to Europe.
