As different parts of the world take different approaches to getting back into the air after the pandemic, passenger traffic at airports worldwide varies. But a snapshot of the world's busiest airports in March 2022 reveals where the airline industry is getting back onto its feet and where it is not.

Data compiled by airline industry analytics business OAG reveals just what airports passengers are heading to. Recently released OAG data ranks the world's 20 busiest airports in March 2022. Mostly they are familiar names, but they also concentrate in regions with very strong domestic markets and except for North Asia, relatively liberal border policies. While US airports figure prominently, there is a respectable spread of top 20 airports around the globe.

Delhi's Indira Gandhi International Airport cracks the top five

Dallas/Fort Worth Airport (DFW) takes fifth spot with 3,413,061 passengers passing through this month. DFW numbers are also down compared to March 2019 levels - 3.2% down.

The busiest airport in the world is?

What is the busiest airport in terms of passenger numbers this month? Take a bow Atlanta's Hartsfield Jackson International (ATL). Atlanta's first place is no real surprise given the key international and domestic airport in Georgia regularly appears in top place. In March, 4,552,931 passengers will move through ATL, a significant margin on the second place getter. Atlanta's numbers are still down 16.4% against March 2019 but up 3.4% compared to February

OAG says of the top 20 busiest airports globally, only Delhi, Denver, and Miami have reached above March 2019 capacity levels in the current month. Beijing remains the furthest behind with just 49% of the level of March 2019 capacity operating this month. Tokyo's Haneda Airport is also considerably behind, with capacity operating at just below two-thirds of March 2019 levels.

OAG notes Heathrow's rebound, with various airlines adding 21% more seats this month compared to February. OAG also gives shout-outs to Paris Charles de Gaulle and Amsterdam's Schiphol Airport where capacity is growing well.
