A message from the UN Secretary General His Excellency António Guterres: ‘On International Civil Aviation Day, we recognize the many contributions of air travel to our world – from connecting societies and delivering vital goods to supporting millions of livelihoods and contributing billions to the global economy. Covid-19 continues to put deep stresses on international aviation, even as increased vaccination rates and testing protocols make air travel possible again. Countries pledged recently to enhance cooperation and risk management, under the auspices of the International Civil Aviation Organization (ICAO).’
