Update - CDG Departures
We flew out of Terminal 2E on Tues, 4/21. Our Delta flight was supposed to take off at 11:45 am, it was delayed to 12:10 pm at the time we left our hotel and further delayed until 12:45pm on take off.
We arrived at the airport around 8:40am. The longest line was at the Delta ticket/self check in/luggage tag kiosks. We went to an assistant who handled printing out our luggage tags and gave us printed boarding passes, then we waited to use the "automated" checked bag drop off. There were 4 or 5 stations, only 2 were working and both had problems - the people using them kept getting their luggage rejected for being over 24 kg. One person who was the first in a group of 4 passengers, all with large suitcases, noted that the scale said it was only 23.5 kg. One attendant was running between the 2 stations that were in use. I managed to go over to the regular check in desk and the attendant quickly weighed my bag (10kg) and accepted it but the other folks were still there struggling. Lesson learned, it's probably easier to use the regular check in desk rather than the self check in/ bag drop kiosks. That's what I usually do but this time the kiosks were right out front and attendants were directing people to them, I didn't see the regular check in desk way in the back until afterward.
As for EES/Passport control departing, it was easy. In fact, the non EU line was faster than the EU line. There was no waiting and the kiosks seem to be operating smoothly. My sister flew out of Terminal 1 (United) around the same time and also breezed through although they had mobility assistance and were flying business class so I don't know if that mattered.
All in all, I'd say the EES system worked well, but like any part of flying, it all depends on the crowds at a given time and if the computers are working well at the time.
