Two new EU systems, one simple test: are you entering Schengen, or just changing planes?
THE SHORT VERSION
Stay airside and fly on to a non-Schengen destination, and neither system touches you. Connect onward inside Schengen, and you enter at your first Schengen airport: EES registers you there. ETIAS is expected in the last quarter of 2026, with a transition period after launch.

Do I register in EES on a layover?
Only if you cross the Schengen external border. Stay airside and fly on to a non-Schengen destination and you never enter, so you do not register. Connect to another Schengen flight and you enter at your first Schengen airport, and that is where EES records you.
Not yet: ETIAS is expected in the last quarter of 2026, followed by a transition period. Once it runs, visa-exempt travelers who enter Schengen will need it. Airport transit without entering is expected to be exempt; confirm on the official ETIAS site before you fly.
