I am thinking of booking a flight from the UK to Germany, via Schiphol. The first flight is with KLM proper, and the second with KLM Cityhopper. There will be 40 minutes from the first flight arriving, and the second departing. SkyScanner are offering this trip. I am an EU-citizen, and the flight will be before Brexit.
According to this TripAdvisor article from 2016, KLM Cityhopper use a remote pier, with a bus transfer. 40 minutes is the recommend minimum.
According to this (How can a traveler challenge the "minimum airport connection time"?), it should be doable in 30 minutes. When will a flight be listed as "short connection" at Amsterdam Schiphol suggests that there is a special "short-connection" queue than I can use.
My Question: Is it likely that an EU-citizen will be able to clear Schengen immigration and change piers in under 40 minutes?
I know that if I miss my connection, it's KLM's responsibility to get me to my destination, however, the only later flight to my destination is with EuroWings (Lufthansa, who are on a different alliance).
