Flight passengers wait past closed security gates during a strike in Frankfurt airport, February 21, 2014. Security workers at Frankfurt airport went on strike on Friday, prompting dozens of flight cancellations and causing delays to travellers passing through Europe's third-largest hub. Union Verdi had called on security staff employed by private firms grouped under the BDSW banner to strike from 0100 GMT until 2200 GMT in a bid to achieve higher pay.
