I have just seen you r going to Switzerland.
See if you can find the French Military frequencies for the relevant areas you will cross, it will help a lot.
If not, route through controlled areas, then at least you are talking to someone & won't be intercepted.
Sometimes they can be touchy with no radio contact.
Often the military don't talk to the civilians & buzz across as if it was 1930, had 2 close ones over France (normally Alphajets) & a Mirage play over Waterloo & 2 F16s use me for fun at the Belgian/Luxembourg Border.
Wish I was with you, but doing ATPLs.
Have fun.
