General Authority of Civil Aviation (GACA) has issued a decision banning all Qatari airlines and aircraft from landing at the Kingdom of Saudi Arabia's airports immediately. It has also prevented all private and commercial airlines registered in the Kingdom from operating to Qatar (both direct and non-direct ) immediately. It has decided to prevent all Qatari airlines and aircraft from crossing the Kingdom of Saudi Arabia's airspace as of from 6/6/2017 at 00:01 according to Coordinated Universal Time (UTC). GACA has 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 have to contact with the Authority within just one week to determine the necessary procedures for continued operation across Saudi airspace. This circular of GACA targets 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.
