I have just flown CDG-SEA on F-GZCI.
Very nice-looking Y cabin with pleasant colors but:
- interactive moving map didn’t work (very frustrating on a 10-hour flight)
- problem of connection with earphones. The earphones provided by AF didn’t work (you could only hear from one ear). It was like this in all the cabin. The passengers which had their one earphones didn’t have problems.
- recline of the seat was too important. So when the passenger in front of you reclines his seat, it gets very claustrophobic (and I am used to fly in Y). This kind of recline would be perfect for 34/35” pitch.

Crew was subpar compared to usual.
The captain gave almost no indication during all the flight.
