Owing to its mostly mountainous terrain, Arunachal Pradesh doesn’t have its own airport. If you want to fly to Arunachal Pradesh, there are two options: the Lilabari Airport in North Lakhimpur and the Lokapriya Gopinath Bordoloi International Airport in Guwahati, both located in Assam. Of these, Lilabari Airport is the closest to Itanagar, the capital of Arunachal Pradesh. There are flights four days a week, mainly from Guwahati and Kolkata.
The distance between Lilabari Airport and Itanagar is 72 kilometers and can be reached in 2 hours. You can take an interstate transport bus or a taxi, both of which are easily available outside the airport. However, if you are looking for better connectivity and more frequent flights, Guwahati Airport is the better option. It receives flights from all major cities of the country like Mumbai, Delhi, Chennai and Kolkata. However, the road distance from Guwahati to Itanagar is about 315 kilometers and takes about 8 hours.
Flights from Guwahati to Lilabari Airport take much less time but cost a little more than traveling by bus or taxi. Guwahati Airport also handles international flights from countries like Thailand, Nepal, Singapore, Malaysia and Japan.
