All three airports handled more than 60 million passengers in 2019, but the pandemic then came along and scorched demand for travel. Hong Kong and Singapore were affected more than most as they don’t have a domestic market to cater to, while transit traffic also slowed due to restrictions on movement. On top of that, for Hong Kong, visitor numbers started slowing in the second half of 2019 as anti-government protests gripped the city.
Hong Kong no longer has the busiest airport for international traffic in Asia after the coronavirus pandemic wiped out travel, leaving South Korea’s Incheon International Airport in top spot, albeit with drastically fewer numbers than previous years.
Hong Kong International Airport handled 8.84 million passengers in 2020, an 88% plunge from the previous year. That sent it down two spots to third, below Seoul’s Incheon and Singapore’s Changi Airport in second. Incheon processed 11.96 million passengers last year, leaving it on top of the pile for the first time ever. Changi handled 11.8 million.
