So this was my first try at using lounge E for Schengen flights. From the time I left the lounge to getting to my A gate was 15 minutes. Area E seemed dead (this was around 18 hours), and there was zero line in the passport control. It seems like coming from gates E back to inside Schengen, you actually use a different half of the shuttle train, and the passport control is also a different section. Can anyone confirm this? I didn't see a single person other than me going this way back. Arrivals go through a slightly different route it seems.
