More and more people are flying after the pandemic, making airports busier than ever. A report by the Airports Council International shows that in 2023, 8.5 billion passengers took to the skies worldwide – a huge jump of 27.2% from the previous year.
This surge in numbers means the world is almost back to pre-pandemic travel levels, with a recovery rate of 93.8% from 2019. The Indira Gandhi International Airport in Delhi has secured 10th position, with a passenger traffic of 72.2 million flyers in 2023.
