IndiGo Airlines (6E, Delhi International) is planning to begin ATR - Avions de Transport Régional (EVX, Toulouse Blagnac) operations by the end of the year. In May this year, the Indian budget carrier announced an order for fifty ATR72-600s with deliveries to begin towards the end of 2017.

Operations will focus primarily on serving Hyderabad, Chennai, Bengaluru International, Mangalore, Madurai and Nagpur and two new Tier-II cities, Tirupati and Rajahmundry. As such, in a statement, IndiGo confirmed the turboprop's inaugural service would take place on December 21 between Hyderabad International and Mangalore Bajpe.

"With the introduction of these flights, IndiGo has taken another step towards providing on-time and a hassle-free travel experience to the passengers of Tier-II & Tier-III cities," it said. "IndiGo is also introducing new ATR flights on its existing network which includes Chennai - Mangalore - Chennai, Hyderabad - Mangalore - Hyderabad, and Hyderabad - Nagpur - Hyderabad. These new routes will further consolidate IndiGo’s position as the fastest growing airline in India."

Aside from the ATRs, IndiGo also operates 117 A320-200s and seventeen A320neo.
