American Airlines Group (AAG) has finalised an order with Brazilian plane maker Embraer to purchase four new E175 jets for $182m at current list prices.

The new order is in addition to a deal placed by AAG in 2013 for 60 E175 aircraft.

Deliveries of the new aircraft are scheduled to begin by the last quarter of this year.

To be equipped with 12 first-class, 20 main cabin extra and 44 main cabin seats, the newly ordered E175s will be operated by AAG subsidiary Envoy.

"This new order continues to show their confidence in the platform."

Embraer commercial aviation North America sales and marketing vice-president Charlie Hillis said: “The E175 has served AAG very well since its entry into service, and this new order continues to show their confidence in the platform.

“We also commend the Envoy team on their exceptional E175 operating performance.

“The market for 70 to 76 seaters is still strong, especially considering all the older 70 seaters needing replacement. Embraer remains the clear leader in that space.”

The latest contract has brought Embraer’s total sale of E175 jets to the North American airlines since 2013 to 336.

Last November, Embraer won a $1.08bn deal from United Airlines to sell 24 of its E175 jets.

The aircraft are expected to be delivered within this year.
