The U.S. airline sector, to say the least, has not offered investors any excitement lately.

The flat-to-declining number of travelers, intense competition, and yet another battle with sky-high fuel prices in 2008 have created an environment that's ripe for further industry consolidation, and sluggish share price gains.

Even so, selected entry points are possible, for high-risk investors only. AMR Corporation (NYSE: AMR), parent company of American Airlines, is one. Here's why:

"The Dreamliner is set to become the most significant new product to hit the airline industry in decades," says Horacio Marquez.

The contributing editor and emerging markets specialist with The Money Map Report states, "Of course, the company that's making the dream machine is Boeing (NYSE: BA), which is consider as compelling an investment as I have ever seen."

"In the world of manufacturing, there's nothing more powerful than a technological leap and right now there's something similar going on in the commercial airplane market.

"Airlines are facing some stiff demands. First, passenger traffic and cargo loads are projected to soar, as are the number of long range flights. Yet soaring oil costs are pressuring carriers to cut back on fuel. Second, carriers are also being pressured to slash carbon emissions and to achieve quieter takeoffs and landings, especially as metropolitan areas become even more congested.

"For jet manufacturers, designing a commercial jet that can do these two critical things is no less a technological miracle than the cell phone was 15 years ago. And Boeing is on the verge of making it happen.

"It's not so easy building an airplane; harder still to develop a new one from scratch and then build it in various pieces around the world to be shipped to one place for final assembly," notes technology expert Mark Mowrey.

The editor of The Prudent Speculator Tech Value Report explains, "No surprise, then, that this month's new buy, aerospace giant The Boeing Company (NYSE: BA), has fallen behind schedule on the 787 Dreamliner." Here is his bullish review.

"Delays aside, the plane remains the most elegant, sophisticated and efficient carrier-class planes in the world, one for which we bet customers are willing to wait.

"We believe the company will move beyond pre-launch troubles this year and continue to innovate along the gamut of its aerospace endeavors, and find the stock's valuation a compelling entry point.

"In addition to a just-identified 3-unit addendum to an existing order for six Dreamliners from Fiji-based Air Pacific, Boeing has racked up orders for 817 of the 787s from 55 different carriers around the globe.

"The airlines were attracted to the advantages the Dreamliner's nearly half composite (instead of a similarly strong, though heavier aluminum and titanium) structure which should utilize 20% less fuel for a given load and range.

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.
