is notching new deals for a total of as many as 56 planes with three airlines: Japan Airlines, Ethiopia's state-owned carrier and Libya's Buraq Air.

Tokyo-based Japan Airlines said Friday that it plans to order 30 "next-generation" 737 planes from Boeing, with an option to purchase 10 more. In a news release, the carrier said it planned to conclude a deal on the 737 next-generation, or "NG," aircraft this spring and put the planes in service next year.

The next-generation 737 series includes the 700, 800 and 900X types. Japan Airlines didn't specify which it was ordering. A Boeing spokeswoman said the mix of types had yet to be determined. List prices for planes in that series of planes range from $50.5 million to $74.0 million, according to Boeing's Web site, suggesting the 30-plane order could be worth as much as $2.22 billion.

Japan Airlines wants to use the planes for a schedule expansion at Tokyo's Haneda Airport.

Elsewhere, Ethiopian Airlines has signed firm orders for five 787 Dreamliners, with options to acquire five more, a Boeing spokeswoman confirmed. Media reports quoted Ethiopian officials saying the deal had a $1.3 billion price tag.

The two deals follow Boeing's confirmation Thursday it has a preliminary deal with Libya's Buraq Air for up to six 737-800 planes. The deal initially involves three planes, with the Tripoli-based carrier holding options to buy three more.

In addition, Chinese airlines last week inked a $7.2 billion deal for 60 of the 787 Dreamliners, Boeing's fuel-efficient twin-aisle plane. Boeing last week changed the plane's name from 7E7 to 787.

Boeing shares rose 77 cents, or 1.5%, to $52.77.
