Mizoram has only one airport, Lengpui Airport, which is near Aizawl, and this airport can be reached from Kolkata by air which will take around 1hr and also from Guwahati by air within a short period of 30 min. The road from the airport to the city takes around another 1 h, and the taxi rate will cost 600 rupees to reach the city. Look out for people who can share the ride as you may be able to pay half that price.You can also try for a shared TATA Sumo which charges 100/- per seat and takes 10 passegers - 2 ahead, 4 in middle and 4 at the back.But make sure that you act very fast and book a seat as there could be just one or two Sumos.
