Sometimes I read so much bad information on here about CDG that I have not connected through there in years. I generally transit through Frankfurt, and I always get lost there, can’t find the right connection board, ask for help and then find my way. So we’re sitting here, waiting to board our flight back to Seattle and I thought I’d weigh in.
On our outbound, we were Seattle-to-Paris-to-Tel Aviv. Delta Airlines and Air France, all on a single Delta ticket. No checked luggage and Business class seats, so front of the plane. We exited our flight from Seattle in Terminal 2E. We did not need to go through anything other than a security check (flying from non-Schengen country to non-Schengen country - this part would be different for many of you). We did need to take a little shuttle bus - took about 10 minutes - boarded it right outside the plane.
Note that if we had checked luggage, it would be checked though to final destination on our single ticket.
Got off bus and then it took us 5 minutes to walk to train to take it to Terminal 2E, K gates. Took the train one stop. Walked around the corner to security. Liquids, laptops and phones out. No line (8am on a Tuesday)
Done in under 30 minutes total. Hope this is helpful -remember it’s for non-Schengen transit only - no immigration check. Return through CDG just now (6am on a Tuesday) was similarly fast and landed at an actual gate so no need for bus on the tarmac.
