Vietnamese budget carrier Vietjet Air (VJA) has signed another agreement to buy GE (General Electric) & Snecma engines in a deal worth some US$800 million after spending US$9 bln to buy 100 Airbus jets in September.

The agreement, which includes technical and maintenance services, was signed early this week during the visit of US Secretary of State John Kerry to Vietnam. The engines will be used for 100 aircrafts that VJA ordered in September.

Regarding GE, this is the second biggest agreement that the company has signed with Vietnamese airlines in the last three months. Earlier, the US-based company reached an agreement with Vietnam Airlines to sell 40 engines to be used in their Boeing 787 Dreamliners.

Though the value of the deal has yet to be disclosed, the price of each engine might vary from $45 to $56 million, depending on the relevant maintenance agreement. Besides GE, other aircraft engine manufacturers include Rolls-Royce and Pratt & Whitney.
