How I can check if my ETIAS is still valid?
From the date that your ETIAS is approved, it will be valid for a period of three years,
or until the passport that it is linked to expires, whichever date is sooner.
During the three years of validity, you are able to use the ETIAS as many
times as you wish, provided that you do not overstay the limit of 90 days in any one trip.
You are able to travel to as many Schengen countries as you wish to within the
three years that your ETIAS is valid. It is also possible to use the ETIAS to
tour around Europe, so if you wanted to travel to France, Spain, Germany
and any other countries within the Schengen zone, you could do that trip
using your ETIAS while it is valid. Alternatively, you can make unlimited
repeat trips to Europe over the course of the three years the ETIAS is valid for.
