Arunachal Pradesh doesn't have an airport, which is presently operational. Itanagar Airport is under construction, and existing state-owned airports like Daporijo Airport, Ziro Airport, Along Airport, Tezu Airport, and Pasighat Airport are small and are not in operation. If you're planning to reach Arunachal Pradesh by airways then the closest option will be Lilabari Airport, which is 57 kilometers from the Itanagar and provides flights Kolkata and Guwahati by an Air India Regional flight. You can also consider taking a helicopter ride to reach the desired destination. Pawan Hans under the aegis of Govt. of Arunachal Pradesh, operate daily passenger service with one Dauphin and Mi-172 helicopter.
