9 Hours in Copenhagen, Denmark
I love taking advantage of long layovers whenever I can. One - these tickets typically end up being cheaper. Two - it’s a quick and easy way to see a new country without having to buy another flight. I’ve done a quick day trip with layovers in Rome, London and Bordeaux. They’ve ranged from 8-12 hours and I typically look for an arrival time before 1pm. That way I can leverage as much daylight as possible! I usually travel with a carry-on (yes even for international trips).
