Sorry for the elementary question, never been to ARN. Planning a mileage run in May. Will arrive on A3 from ATH and return on same aircraft 50 mins later.

Do arriving Schengen passengers disembark into the departure area or is there a separate arrivals level at ARN, in other words, do arriving passengers have to exit the secure area and re-enter or can they just stay in the secure area?

Thanks for the help.
