“2021 represents the beginning of the aviation industry’s recovery,” said ACI World director general Luis Felipe de Oliveira. “While some of the perennial busiest airport leaders have re-joined upper ranks, other regions struggle to recover leading to new entrants in the top 20.”

From the top 20 rankings, almost all airports have significant domestic traffic representing 65% to 100% of their total passengers. The only exception is Istanbul (IST), which has a larger international traffic share of 72%.
