Just returned yesterday from a trip to Spain with connections at CDG both ways.
Our outbound flight arrived at CDG on Thursday, 9/21 and we had a 1 hour 45 minute connection. Our flight arrived early, so we actually had about 2 hours. Border control was a nightmare and after we finally got through we ran and arrived at the gate about 15 minutes before departure.
Returning Sunday 10/1 was even worse. Our connection was 1 hour 45 minutes again and we arrived on time. Long lines at border control again with only 3 windows open. We finally got through at 10:02 and our flight was 10:20, so we ran. We got to the buses to go to terminal M to find another huge line. We had to wait through multiple buses and got off the bus at 10:20. DH ran ahead and I got to the gate as fast as I could behind him. Thankfully we were able to get on the flight! At departure time Delta had 47 passengers missing so they ended up holding the flight for 25 minutes.
We've transferred at CDG before with no issues, but the last time was 2015.
