Hello,

I‘m currently in the process of planning a vacation and a bit unsure whether I should use a multi-city ticket in this specific case.
Probably good to mention it at the beginning: There is no „hard“ need for the multi-city ticket, it would mostly be for reasons of personal convenience and wanting to try flying AF (also I wouldn‘t mind the XP for the additional segment). Ticket prices maybe differ by around tens of Euros, so that isn‘t that much of a bother either.
To my plan: The goal would be to get to NYC. The starting airport most convenient to us (by a relatively wide margin) is served by KLM only. When looking for tickets last week AF and KLM offered a flight connecting in AMS and CDG, the trans-Atlantic segment operated by AF. When looking today, they don‘t seem to want me to sell this connection (I would still be able to book all of the individual flights, so I assume they all still exist).
I would be able to replicate the original flight plan by using multi-city ticketing (X-CDG via AMS; CDG-JFK; JFK-X via AMS) though, time to connect in CDG would be around 2,5 hours.
This would only be „necessary“ this way, return via one-stop in AMS is fine.
Would we able to get bags checked through to JFK at our departing airport if all the segments are on a single ticket?
Would the transfer in CDG differ from a transfer done without a multi-city ticket?
Is there anything we should be aware of?
Or is the whole idea silly to begin with?

Thank you!
