With Boeing Co. (NYSE: BA) having now showcased its new 787 Dreamliner, investors might wonder if it is too late to invest. According to three newsletter advisors, there are still upside opportunities. One looks at Boeing itself, one spots value in an aircraft seat and interior designer, and one looks at an aircraft leasing play.

Boeing is a buy for longer-term investors from Bernie Schaeffer, who recommends the shares in his Power Stocks advisory.

Technically, the advisor notes that Boeing recently broke out after a lengthy sideways consolidation. From mid-November 2006 to the middle of last month, he points out that the stock traded in a narrow range between $85 and $92. He explains, "Such long periods of sideways movement can be followed by extended trends."

That level, he now says, should hold as support and should serve as a "foundation for higher prices." Further, he adds, the stock's rise above $100 is "psychologically significant" and should offer additional support for the stock.

The contrarian advisor notes, "Even with the strong fundamental and technical backdrop, Wall Street remains fairly pessimistic. According to Zacks, nine of the 18 analysts rate the stock a 'hold' or worse and three of those have a 'strong sell' rating on it. Any upgrades or upward price target revisions from this skeptical crowd could boost the stock."

Meanwhile, he maintains a target price for the stock is $127 a share. In addition to investing in Boeing itself, there are two ancillary companies that couldl benefit from the success of the Dreamliner.

On STOP TRADING! on CNBC today, Cramer said the Fed is actually listening to the guidance conference calls of the major companies and seeing the slowdown. The tape is not lying, and these guys that say the Fed will hike must be condo buyers. Stocks to Cramer are telling the real story, the Fed isn't. Cramer noted his 17% gain predicted on the DJIA.

Cramer loves The Boeing Co. (NYSE:BA), and the ones saying the cycle is over are giving investors a gift. The bears are wrong here according to him. He also noted BE Aerospace, Inc. (NASDAQ:BEAV) as a beneficiary there.
