Mmm if you don't want to wait for better/clearer information about possible direct flights from Thailand to France after July 1st, then yes that might do the trick to start planning now...
These are not official sources but coming from a visa agency
1.
Flights from Iceland to France should be allowed already from June 15 (as flight from EU to Iceland).

2. Without much details given, it reports that one American (coming from EU) was not allowed to enter Iceland.
