Georgian Airways (A9, Tbilisi) has retired its single B737-300 and B737-400 in spring but has however added a second ex-Xiamen Airlines (MF/Xiamen) B737-500 that it operates on behalf of the United Nations. It has resumed three times weekly scheduled B737-500/-700 service from Tbilisi to Moscow Domodedovo on August 20 following a lift of the ban on scheduled flights between Georgia and Russia that had been imposed following the short war between the two countries. It had previously operated several charter services on the route with special approval from the Russian authorities. Georgian Airways has started codesharing on the twice daily Yerevan-Tbilisi services operated by Armavia (U8/Yerevan). Georgia has signed an open skies agreement with the European Union allowing all EU carriers to operate to the country from any EU airport.
