What ID Do You Need to Fly from Arlanda Within Schengen?

Within the Schengen area there's no immigration border control in the way there is entering from outside it, but you still need to show identification to check in, drop bags and board — and each airline sets its own accepted document list for that step, based on its own policies and the passenger's nationality.

That means the honest answer to "is a national ID card enough" is: check your airline's own terms for your route and nationality, rather than assuming what worked on a previous trip still applies.

Swedish nationals travelling within Schengen commonly use a Swedish national ID card or a passport; other EU/EEA nationals living in Sweden typically use their home country's national ID card where their airline accepts it. If you're travelling on a residence permit or a non-EU passport, check your specific airline's accepted-documents page rather than assuming a national ID card from your home country covers it.

Your airline's own website is the definitive source for what it will accept at check-in for your specific route — search its "travel documents" or "check-in requirements" page for your destination. If you want the broader EU framework behind it, the European Commission publishes guidance on Schengen area travel and accepted identity documents.

Getting this wrong at the desk is one of the more avoidable ways to lose time before a flight, so it's worth confirming the accepted document the week before you travel, not the morning of. Once you know what you're bringing, the rest of the departure — check-in, security, the gate — runs on the same timeline as any other flight.

The same airline-sets-the-rule principle applies to children travelling with you — a child's own national ID card or passport requirements, and whether a family can travel on a single document in any circumstance, are set by the airline for its own flights, not by a general Schengen rule. If you're travelling with children, check the airline's requirements for each passenger individually rather than assuming a rule that applies to adults covers the whole family.

Even within Schengen, where formal border checks don't apply the same way, airlines still commonly refuse to carry passengers whose ID document has expired or is very close to expiry, since the document needs to remain valid for the return journey too in many cases. Check the expiry date on whichever document you plan to travel with well before your flight, not the same week — a national ID card or passport renewal can take longer than expected if you leave it late.
