Transfers of under an hour with AF/KLM are a complete crapshoot; if you actually need to get to your destination on time (as opposed to somewhere within half a day of that), don’t use them (otherwise, go for it).
For several years pre-Covid, AF/KLM would sell you evening tickets from Moscow SVO to Paris CDG with a transfer of IIRC half an hour to an hour and a half in AMS, and they virtually never made it, putting you up in the airport hotel until the next flight in the morning. It wasn’t a bad deal if you expected the delay (I still carry around one of the very nice foldable hairbrushes they gave out in the hotel), but I don’t understand how that could ever be a sensible business decision.
I’ve never had issues with KLM (aside from the one time when there was a warzone in flux directly beneath their flight path, I can kind of forgive them for that).
AF and especially CDG though. That whole place is a shitshow. At least Schiphol allows you to run to wherever you need to be instead of cooling your heels waiting for the shuttle to arrive.
I just had a delayed flight out of ATL and missed my 2pm connection at CDG, next flight was 9pm. Delta gave me 15k sky miles, better than nothing I guess.
