Long queues formed at Copenhagen Airport on Thursday as new security routines took effect, with delays expected to continue through Friday and the weekend.

The airport deployed extra staff to manage the backlog, but lines stretched hundreds of meters between terminals two and three, according to Swedish broadcaster Expressen. SAS estimated that 250 passengers missed their flights on Thursday due to the delays. Travelers were advised to arrive at least two hours before Schengen flights and three hours before non-Schengen departures.

A Swedish traveler described the queues as calm despite their length, with the airport urging passengers to plan additional time for security checks. The disruptions follow the implementation of unspecified new security measures, which have not been detailed by authorities.
