Ryanair has named seven popular European airports where passengers are suffering long delays because of the EU border checks introduced in April. The airline said these sites are “not ready” to manage the high passenger volumes during the peak summer season because of “insufficient staff, kiosks and system readiness” after the introduction of the Schengen Entry/Exit System (EES).

The majority of UK travellers carry out the process at foreign airports, but the Port of Dover, Eurotunnel’s Folkestone terminal, and London St Pancras railway station are also affected.

The European Commission, as well as its president Ursula von der Leyen, has been urged to “act now” amid the lengthy delays caused by the rollout of the border checks associated with EES.
