For the past half year, flights from Euroairport to many Schengen destinations, such as Amsterdam, Munich, Berlin, Vienna and Heraklion, have consistently been leaving from non-Schengen gates.
Does this measure have a set duration?
Assuming that this is due to the current Schengen border suspensions and not some internal operational reasons at the airport, you will find the current expected end date here: https://ec.europa.eu/home-affairs/what-we-do/policies/borders-and-visas/schengen/reintroduction-border-control_en
However, some of these suspensions have been repeatedly extended and may well be again.
