Practical takeaways
- The top three (Japan, China, Vietnam) take 58.8% of all departing passengers, out of 53 countries.
- China is served at the most airports, 44 of them — not necessarily the same as ranking first by passengers.
- The heaviest loads go to United Arab Emirates, about 360 passengers a flight — long-haul routes flown with large aircraft rise here.
