Recently, ForwardKeys analyzed and reviewed the eight major travel trends this year. First of all, China's Southern Airlines, Eastern Airlines, Air China, Shenzhen Airlines, Hainan Airlines and Xiamen Airlines have successfully entered the world's TOP20 airlines. It is understood that among the global TOP20 airlines released in 2019, China Southern Airlines, Eastern Airlines, and Air China are already listed, while Shenzhen Airlines, Hainan Airlines, and Xiamen Airlines are newly included in the global TOP20 airlines this year. Throughout the list, the ranking of major European airlines has declined or has been squeezed out of the world's TOP20 airlines. The two largest European airlines, Ryanair and EasyJet, have dropped from 5th and 8th to No. At 7th and 16th place, the old European airlines Lufthansa, British Airways, and Air France fell out of the world's TOP20 airlines. In addition, Emirates and Air Canada also fell off the list, but JetBlue and Spirit Airlines of the United States successfully made the list this time.

In addition, the status of an international aviation hub has changed, Doha surpassed Dubai to become the most important hub airport in the Middle East, and Amsterdam surpassed Frankfurt in Europe. The demand for long-distance travel is declining, and domestic travel is dominated. The emergence of new coronavirus variants threatens the aviation industry. Leisure tourism in the United States has promoted economic recovery, Central America and the Caribbean have the strongest recovery, and the Middle East has begun to recover.
