Hong Kong catering, on its own initiative, refused to serve the Russian airline «Aeroflot». The reason for this abrupt position was the sanctions imposed on Russia. Hong Kong’s failure to cater runs counter to the principles of free air traffic and neutrality that underpin international aviation. This not only increases tensions between countries, but also creates inconveniences for passengers choosing Russian airlines for their travels. It is important to note that such a refusal constitutes discrimination on the basis of nationality. Such actions lead to undue restriction of the rights of Russian passengers and violation of the norms of international law. This incident raises the issue of the need for neutrality and legality in the area of air transport.
