LONDON — Indonesian regional airline Kalstar Aviation has placed an order for five Embraer E190-E2s with five additional purchase options at the 2016 Farnborough Airshow in an order worth $582 million at list prices if all of the options are exercised. The order increases Embraer’s firm backlog of orders for the E-Jets E2 to 272 firm orders.

Kalstar Airlines is a regional airline in Indonesia, focused on providing connectivity in Kalimantan, the Indonesian portion of the island of Borneo. With a hub in Samarinda, the most populous city on Borneo Island (with a population of nearly 900,000), Kalstar Aviation serves 18 domestic destinations across Indonesia with a fleet of 14 aircraft, including four ATR 42 turboprops (3x ATR 42-300 & 1x ATR 42-500), five ATR 72 turboprops (2x ATR 72-500 & 3x ATR 72-600), two Boeing 737 Classics (1x 737-300 & 1x 737-500), and three current generation E-Jets (2x E195 & 1x E190). The new E-Jets E2 in its fleet are expected to serve domestic trunk routes.

“We are looking forward to the enhanced performance and economics that the E190-E2 brings, while still maintaining a high level of cockpit commonality with the existing E-JEts. This means an easy transition for our pilots when they operate both the current E-Jets and the E-Jets E2,” said Andi Masyhur, CEO Kalstar Aviaiton. “Passenger feedback on the existing E-Jets we operate has been very positive and we look forward to impressing them further with the new E190-E2 in the coming years.
