flight change in Amsterdam

With the usual comment - if everything is on time. You should be behind security so it is just a gate switch.

I didn't know flights between Paris and Schipol Amsterdam still existed:) Most people take the high-speed Thalys train between Paris and Amsterdam, as it's faster. In any event one hour is enough time for the connection. You'll have to pass through an immigration checkpoint at AMS before you reach your gate. There is usually an express lane open for people with tight connections. There will be a monitor overhead showing which flight qualify. At Schipol the security check for transatlantic flights is done at the gate instead of a centralized area. So as long as make it to the gate before they close the doors on the plane you're good.

Michael, there are even a couple turboprop Schiphol-Zaventem (Bruxelles) flights. They are useful for people making multiple connections from/to transcontinental flights. However, KLM/Air France sell some Thalys tickets as if they were airplane trips. They even have a IATA cod for Gare du Nord and a shadow "ariline" code for Thalys operating in "code-share" with AirFrance

It was a joke. FYI, KLM/Air France are part of the consortium that own the high-speed train line between Brussels and Amsterdam. So whether one flies or trains it between Paris and Amsterdam they make money off of it.
