Arrived from Brussels with Thalys to AMS today around 2pm. Took me about 1 hour to clear security and immigration. Complete clusterf**k . I was told to go one way for SP, which turned out to be only a regular line for all passengers. Ended up queueing for about 45 min until I reached security. Passport control was done through autmated gates and was rather fast compared to the previous line. Our flight was delayed about 1 hour to wait for PAX (we ended up leaving with about 20% of checked in pax not onboard (SV flight)).
