Indian carrier Air Costa on Thursday ordered 50 E-Jets E2 aircraft from Brazilian manufacturer Embraer worth $2.94 billion, both companies announced.
The deal with Air Costa also includes purchase rights for 50 more of the aircraft.
With the orders, Air Costa will become the first customer of the E-Jet E2 in the Indian market when it takes the first delivery in 2018, Embraer said in a statement.
Air Costa executives said they will use the jets to fly routes in secondary and tertiary markets in India.
Air Costa is part of India's LEPL Group, a diversified company with interests in property and infrastructure development.
The airline started operations in October last year serving several second-tier Indian cities.
