I did learn all the maps to understand layout so was well prepared to transit trough it last week. It worked. Signage there is useless as it doesn't explain difference between Shengen and non-Schengen wings. Went through both terminals. Overall impression was very depressing. Badly planned and poorly managed. I had no problem at security due to late departure time. Otherwise ten minutes spent on scanning my bag wouldn't work in big crowd. Immigration had just one manned desk for all outbound non-EU traffic. Regular passengers crews fast track - all served in one line in total chaos by one officer. I gave up my turn in the line for 12 crew members 2 business class passengers and one family with a baby. So many people jumping the queue before me! On arrival with Lufthansa from Nice we were parked somewhere within 10 minutes bus ride. Arrival hall had just one narrow escalator (supermarket type) for 300 people with hand luggage. On departure we were asked to use automated gate with bar code readers with no staff to assist. Many people with home printed and mobile boarding passes were confused with no help at all. Staff at the restaurant landside near b24 gate didn't speak English. Toilets near gates packed with people and not very clean.
