RAk is in my opinion the worst airport experience. No online check in so you need to visit a standard check in desk. There are priority for Club Europe and Status pax bit as others have said you need to go through security to enter the building. This can be from 10-45 mins or more. You then have to queue for immigration make sure you have your exit card, and security. Then a customs check your passport is stamped out check. He lounge.. well it’s the first time I’ve walked out and had a burger and soft drink in he terminal. Godawful place.
I wouldn’t bank on having much free time between the queues and document checks/ formalities. FYI the airport cat is usually found at the check in desks by the flaps that the luggage go through.
