India's network has a stable core of long-running routes surrounded by a volatile fringe of short-lived regional connections.
What this shows: The chart plots Number of routes.
Conditions and method
A route is a city pair with more than 1,000 passengers in the year, with the airports of one city counted together. The charts use 9 observed years (2016 to 2025). 2019 is missing from the source. 2015 and 2026 have fewer than 11 months and are left out. With so few points the charts describe the series and test no trend.
