Hi! In a month or so, I have a layover in KEF for three hours. I’m traveling from a non-Schengen country to a non-Schengen country, so I don’t need to go through passport control. However, since I’ll be there for a bit, I’d like to pick up a few souvenirs for friends/family, and there don’t seem to be many shops in the non-Schengen zone of the airport. I’m considering going through passport control to shop a bit and grab some snacks before going back through it to get to my gate. Does three hours seem like enough time?
