There's been a lot of recent news about airplane maker Boeing (BA -0.87%)-- and no, not just about dropping a few 737 fuselages into a Montana river. 

It was recently announced that Norwegian Air had put in an order for 20 new Boeing 787s. According to Motley Fool analyst Blake Bos, that's the biggest order Boeing has received for the planes in 2014. Blake says that the average price for a new 787 was $250 million in 2013, and if that price holds true, it means Boeing just accepted a $5 billion order. Considering that there's a lot of speculation on Wall Street that Boeing has yet to break even on these incredibly expensive planes, this new large order bodes well for the company.

On top of that, the Export-Import Bank needs to be reauthorized by the end of September. The bank gives companies cheap financing for exporting goods overseas; it provided Boeing with about $48 billion over the last five years. It's up to Congress to reauthorize the bank by Sept. 30. 

So what should investors care more about, the 787s or the bank? Blake says that while the 787 order is a pretty good deal for the company, the reauthorization of the bank remains a much more important factor for Boeing. He believes that all Boeing investors need to keep a close eye on what Congress decides about the bank before diving in.
