A new firm order for seven E190 airliners from Venezuela’s Conviasa led Embraer’s commercial activity here yesterday. The deal involved a conversion of options from an order placed in July 2012 and raised Conviasa’s firm order count to 13 E190s. It still holds options for another seven.

Embraer also identified Japan Airlines as the customer for an order for four more E170s. With that deal, JAL has now placed firm orders for 15 E170s.

Other Embraer-related news involved Air Costa of Vijayawada, India, which has acquired three E-Jets for launch of its scheduled regional airline service in India. Air Costa has arranged delivery of two E170s via ECC Leasing, Embraer’s wholly-owned subsidiary. The new carrier has also bought a single new E190 from Embraer. That firm order already appeared in Embraer’s backlog as business from an undisclosed customer.

Finally, a new commercial airline in Europe, Air Lituanica of Vilnius, Lithuania, has acquired two Embraer E-Jets. The carrier plans to launch scheduled service on June 30 with one E170 leased from a third party. In July, Air Lituanica also plans to add an E175 leased from ECC Leasing.
