I can now report that it was very easy to leave CDG today (exited on French passport). I had made myself an “international business executive” attestation but I didn’t even have to show it anyone.

the border patrol officer told me all flights are cancelled after Monday (but I don’t think he knows what he’s talking about)

I asked the AF lounge staff RE next few weeks. They said they expect frequencies to decrease but destinations to stay similar to what they have today.

side note for anyone interested: Apparently the UK will be enforcing some sort of exit ban on non-work related trips. Still TBC
