Traffic in Vietnam is heavily concentrated: Tan Son Nhat International Airport (SGN) alone handles about 41.2 million passengers a year, roughly 59% of the 70 million across the 3 airports listed here. That pattern is typical of a country with one dominant hub carrier feeding a single gateway.
Between them these airports operate 6 runways serving 3 cities, all on a single national clock. Every airport below links to a live map of aircraft observed within available ADS-B coverage around the field.
The next airport in the ranking is Noi Bai International Airport (HAN) at about 29.0 million passengers. The gap to SGN is 12.2 million, while the three busiest airports account for roughly 100% of traffic represented by this list. Most listed traffic is therefore concentrated at the top of the network.
The airports are spread across roughly 10 degrees of latitude and 2 degrees of longitude. The network is geographically compact enough that most domestic sectors remain comparatively short. Field elevations vary less dramatically than they do in the world's mountain-airport networks. The average across this selected set is 2.0 runways per airport.
Read airport by airport, the selected Vietnam network is not interchangeable: Tan Son Nhat International Airport (SGN) has 2 runways and about 41.2 million annual passengers, Noi Bai International Airport (HAN) has 2 runways and about 29.0 million annual passengers and Da Nang International Airport (DAD) has 2 runways and no comparable traffic figure. Those differences matter when comparing a live map. A larger passenger total indicates schedule scale, while runway count describes physical layout; neither number by itself proves how delayed, connected or operationally efficient an airport will be on a particular day.
With 3 gateways in this data cut, the Vietnam hierarchy is readable directly: SGN contributes 59% of the represented passenger total, HAN contributes 41% of the represented passenger total and DAD contributes 0% of the represented passenger total. That makes SGN the first gateway here without reducing HAN to a minor field, since its traffic is about 70% of SGN's.
The physical ranking differs from the traffic ranking: SGN has 2 listed runways, HAN has 2 listed runways and DAD has 2 listed runways. HAN is the highest of the group at 39 ft, against 33 ft at DAD. Those facts describe layout and setting, not a live capacity forecast; weather, active runway configuration and traffic flow still decide what a viewer sees on the map at a given hour.
