Does anyone know how they track passports in Scandinavia? I Traveled to Denmark last Christmas and have two passports as dual citizen with Canada/USA. I do not see an exit stamp on one of the passports that I used nor do I have a ticket that reflects the exit date so I was thinking of just using the other passport to avoid any issues as this has happened in once long ago in AMS and was a huge problem and hours later to get resolved. Any suggestions?
We have only ever traveled with one passport. I would go with the passport where you currently live.
Where did your actual return international flight leg originate - Denmark or through a connecting Schengen country? For example, if you flew from Denmark to the Netherlands (AMS) or France (CDG) and then boarded a flight for your international destination then your exit stamp may be from either of those countries.
