Saleh Haroun , Director of the Air Transport and Airport Affairs Department at the Qatar Civil Aviation Authority, said Monday that Doha International Airport is considered one of the best airports worldwide based on its record in the fields of safety and security. Speaking to journalists here today on the occasion of implementing a new safety system including APP which handles the passengers\'\' documents and PNR which specializes in Passengers\'\' data. He said that the system identifies the passenger of a particular trip, 24 hours before boarding which helps in capturing suspicious passengers before entering the country or boarding the plane. He added that the system can identify whether the passenger was blacklisted or has a police record as soon as they book a ticket. Haroun said that airlines working in Qatar, with the exception of European ones, all signed an agreement to provide the Authority with the necessary information on their passengers. (QNA) M B/MD
