We are flying business class on Dl160 MSP-AMS arriving in AMS at 6:20am. We have a 3h25m layover then at 9:45am fly KLM 1363 European business class from AMS to WAW. We know what European business class is and will not be surprised. Question is what to expect? In recent years all our European flights have been wholely in the EU. Only at FRA did we even see a Schengen and non-Schengen area. We know there are lounges in both areas. We don't know which area we fly into and which area we fly out of. We don't know what to expect by way of immigration and customs experiences? We don't know whether we have to handle checked through luggage. We don't know what is a must see at the airport and how early things open. When we arrive WAW will we have to go through immigration and customs? All advice is welcomed.
