2E to 2F at CDG airport

Arriving from USA you will have to go through Schengen Immigration and get your passports stamped. 2E is across the access road from 2F, but that is the least of your worries. How long it takes to clear immigration is the limiting factor. Are the flights on the same airline (Air France?) so they can put you on a later flight if you miss your scheduled one?

Is your USA to Toulouse all a single booking?

Did you book USA-CDG and CDG-TLS separately?

What is "limited" time to change planes?

Any hope of giving you useful answers is dependent on those details

Thank you for the input. I booked the air travel through Air France, but the flight is being operated by Delta. Newark,NJ to Paris is Delta and Paris to Toulouse is Air France. Our return trip home will be through Delta (but that was done as a separate return flight).

The flight to Toulouse was offered as a single purchase using both Delta and Air France with 1 hour and 40 or so minutes between flights. I assume that our luggage will be transferred from 1 plane to the other plane.

I don't understand what "Schengen Immigration" is. Do we have enough time between flights? Thank you again!

No you don't have enough time between flights.

You are arriving from a foreign country on a very large plane. Unless you are siting right by the door, it will take you 15 - 20 minutes to just get off the plane. Then you have to walk to immigration. You have to go through passport check (Schengen immigration) which depending on the time of day can be very slow. You have to change terminals. I don't know if those terminals are connected inside security or not meaning you may have to go through security to get into the terminal to catch your connection. If your inbound flight is late, you have missed your flight. If you don't walk very fast, you missed your flight.

While I'm sure they booked what is a "legal" connection, I would want 3 hours between flights.

There is this from the CDG website:

Enter "2E" in the "from" block, and "2F" in the "to" block and see what it says.

I don't understand what "Schengen Immigration" is.

I can't believe that in these days of all the nightly news shouting "ICE" and "building a wall" that you did not realize that when you enter a foreign country, they check your passport to see if you are a criminal or a terrorist, or somebody they don't want in their country or the other countries who have joined together in a uniform immigration zone called Schengen. Enter one country, and you have entered all of them, since there is no longer passport checks between them.

A few years ago I had two intra-European/Schengen flights (Nice-CDG-Dublin) on small Air France planes, changing between 2E and 2F. I had no passport controls because this was inside Europe, only the outgoing security check. Even then, with my one-hour to change, I barely made the second flight and I was moving fast.

I did find a EWR-TLS on the Delta site with a 1h50m stop in CDG.

Another option is EWR-DTW-CDG-TLS, with the CDG stop 1h40m

It seems, if this is what OP has, Delta believes the transfer is possible

If I were OP I would acquaint myself with what flights are available from CDG-TLS, in case the connection is missed, so I could be prepared to continue on in the most expeditious manner and not just the most convenient for the airline (AF)

Air France has 6 flights a day from CDG to Toulouse, from 7:25 am to 9:00 pm. Should be something there they can put you on if you miss your assigned flight.

In May we arrived in 2E (Delta flight from Boston) walked to 2F & we waited almost two and half hours getting through immigration at 2F. Yes our bags were checked through but you still have to go through passport control.

I would think this would be fine. they sold you the ticket, it's all tied together. They think you can make the flight -- and if not, as someone pointed out earlier, AF has several flights a day to Toulouse, so they will put you on a later one.
