More positives for Boeing

The news comes on the heels of other positive developments that have boosted Boeing's falling star in recent weeks.

The airline maker is reportedly ready to sell a new version of its 777 jetliner, dubbed the 777x.

According to Aviation Week, Boeing's board of directors is expected to decide as early as its next meeting in April whether to give the Commercial Airplanes division authority to offer the proposed 777X derivative to airlines.

In other news, there are rumors Irish low-cost airline Ryanair will soon announce an US$18 billion deal to purchase up to 200 737 jets from Boeing, pushing the latter's stock up to a five-year high.
