Top 10 largest airports in the world.
The ranking list is based on the actual area of the airport.
The airport’s planned area is usually huge, especially in desert areas, the land is vast and cheap, and without considering the cost of land, the planned size of the airport may be huge.
However, our website is based on actual engineering. What needs to be judged is airport engineering, not the land area.
We ranked the actual land development area of each airport this time, including the airport runway, terminal, office building, parking lot, control center, and other auxiliary facilities.
Does not include undeveloped wasteland.
Such a list reflects the actual engineering scale of the airport.
To maintain the list’s accuracy, the list will be updated in real-time.
