Brazil’s Embraer has received a a purchase order from Air Costa, a startup airline in India, for 50 E-Jet E2 passenger planes in a contract valued at $2.94 billion.  Air Costa also has an option to order an additional 50 planes, which, if exercised, would swell the size of the potential order to $5.88 billion, Embraer said.  The order makes Air Costa the first customer for the E-Jet E2 planes in India, with the delivery of the first E190-E2 plane scheduled in 2018. The E195-E2 plane would be used commercially in 2019.
