Heads up: looks like the 17th is going to be a mess. Was connecting through CDG (routing ATL-CDG-VCE; ATL-CDG on DL is fine) - AF cancelled the 09h40 flight and rebooked me a day earlier, i.e. when I'll be in the air from the states. Looks like all other flights on the 17th are also zeroed out, incl. legs via AMS. DL is currently working the mess that AF created, so we shall see... in the last year, this has happened to me 5 of 8 times connecting through CDG...
