I know this is an unusual itinerary, but I may have to do this because of inflexible dates and limited miles to spend on two different airlines. I may take a TN flight LAX-CDG. My next flight, on a totally separate ticket, would be AF from CDG-NAP.

Can someone please help with what Gate/Terminal the TN flight will likely land in and then where the AF flight will depart? And where does security and immigration come in? I will have carry-on only, and I want to leave a very safe and long connection time. Thank you!
