Dubai International Airport (DXB), the world’s busiest airport for international traffic, welcomed 44.9 million passengers in the first half of the year, the airports operator said, noting strong demand from key markets such as India and the resurgence of China. Traffic from China, which was hard hit by restrictions during the Covid-19 pandemic, exceeded one million passengers, up 80 per cent year-on-year and representing 90 per cent of 2019 levels.
