A breakdown in the Istanbul provincial security directorate’s PolNet data system left at least 1,000 passengers at Istanbul’s Sabiha Gökçen Airport, unable to embark early on Tuesday.
Many passengers missed their flights as long queues formed at passport control points, security officials said.
Officials said the flight tickets of all those who missed flights would be changed without a fee.
The breakdown was reportedly solved at about 12:30 pm, as operations returned to normal.
A similar data system breakdown occurred on May 19, 2016 at Istanbul’s International Atatürk Airport.
Long queues formed at the main entrance of the airport early on September 26, as passenger became angry at having to wait.
“This is a total disaster. We came here at 6 am and no officials have addressed the issue. We cannot even see any of them around,” one passenger said.
PolNet is the computer network and information system of Turkey’s national police force.
