Long security queues at Copenhagen Airport forced airlines to rebook or delay hundreds of passengers. The Local Denmark, Berlingske, and DR all reported the disruption. SAS said 352 of its passengers were moved to later flights after waits at security. The Local and Berlingske carried that figure. Norwegian said more than 200 of its travelers were affected. The Local put the number missing flights at about 230.

SAS and Norwegian together saw more than 500 passengers hit by the delays, Berlingske and The Local said. The airlines advised travelers to arrive more than two hours before departure. DR said the airport expected more busy periods over the weekend. A Transport Authority inspection required extra security measures. Wait times earlier Saturday reached 45 minutes to an hour at times. They later eased to about 10 to 15 minutes, DR reported.

Airport and authority officials did not say why the tighter checks were ordered. DR reported that silence. Travelers heading through Kastrup this weekend still face the risk of longer lines.

Copenhagen Airport is the main Nordic hub, so long lines ripple into Sweden and beyond. SAS and Norwegian carry most of the short-haul traffic through Kastrup. DR said the airport was still asking people to allow extra time. The Local said both airlines shared travelers' frustration in comments to Danish media. Weekend leisure trips are the next test of the new screening steps.

Tour groups and transfer passengers feel queue spikes first. A missed short-haul flight can strand people overnight. Berlingske stressed the SAS rebooking total of 352. The Local added Norwegian's missed-flight count near 230. DR's weekend warning means the story is not finished.

What we know: Security lines at Copenhagen led to hundreds of SAS and Norwegian rebookings, with more weekend waits expected.
What we don't: How long the extra screening rules will last, and the full passenger total across all airlines.
