Jet Airways plane lands at Lengpui Airport in Aizawl, Mizoram, India.

Lengpui Airport is an domestic airport in Aizawl, Mizoram, India.

The airport is connected by daily flights with Kolkata and Guwahati and three flights a week with Imphal and is located at a distance of 32 km from Aizawl, the capital of Mizoram. Lengpui Airport is the first large airport in the country to be built by the State Government.

The airport was constructed at a cost of ₹ 97.92 crores and was completed in a record time of two years and two months. The construction work started in December 1995 and completed in February 1998. The Airport is expected to be able to cater to 300 incoming and outgoing passengers. Before the construction of this airport, Aizawl was 130 km (81 mi) from the nearest railway head at Bairabi and 205 km (127 mi) from the nearest airport at Silchar. With regards to land acquisition it has been found out that about 65 percent of the area acquired, belonged to some high government officials and political leaders at Aizawl who started buying plots from people in Lengpui village at very low prices. They then donated the land to the government for the airport for which the rich persons got much more compensation as donors than the actual farmers. Previously, Lengpui was also served by Air Deccan which later became Kingfisher Red but the airlines stopped operating from Lengpui on April 2012.

At present, Lengpui Airport has installed Cat-I Instrument Landing System. which will help planes land safely during low visibility conditions. A Runway safety area and Isolatio
