Next data point, Sat 25/6 19:22. Arrived by train 19:03. Was in lounge 25 twelve (12!) minutes later. Absolutely zero pax in the priority line. Almost zero pax in the normal line. My one little day back went to secondary, unfortunately, causing 3 minutes of delay. The flashy machines still cannot deal with coins, it seems. Sit by the moment I post this on a table packed with food & drinks. Twelve minutes is for me the absolute record in the 20 years I fly regularly.
My conclusion after four late afternoon/evening flights since early May: at such times Schiphol seems in normal shape. Although results from the past may not guarantee results in future.
