General Authority of Civil Aviation (GACA) has issued a decision – effective immediately- banning all Qatari airlines and aircraft from landing at the Kingdom of Saudi Arabia’s airports, Saudi Press Agency reported.

It also prevented all private and commercial airlines registered in the Kingdom from operating to Qatar (both direct and non-direct), SPA said.

Furthermore, GACA decided to prevent all Qatari airlines and aircraft from crossing the Kingdom of Saudi Arabia’s airspace as of 6/6/2017 at 00:01 according to Coordinated Universal Time (UTC), the agency said.

GACA pointed out that all airlines and non-registered aircraft in the Kingdom or Qatar wishing to cross the Kingdom’s airspace from the State of Qatar and to it have to contact the Authority within a week to determine the necessary procedures for continued operation across Saudi airspace.

This circular of GACA includes all airlines operating from and to Saudi airports based on the statement issued by the Kingdom of Saudi Arabia regarding the severing of diplomatic and consular relations with the State of Qatar.

Saudi Arabian Airlines (Saudia) also announced on its official Twitter account Monday that it has suspended all flights to Qatar.
