"There are several ways to play the airline industry without buying the airlines themselves." explains Benjamin Shepard, a research editor for Personal Finance. Here, he looks seven stocks that are poised to profit as the sector "gets its wings again."

Hexcel Corp. (NYSE: HXL), he notes, is the largest producer of woven carbon-fiber sheets, which are extremely important for both Boeing's new 787 Dreamliner, as well as for the new Airbus A380. He rates thes tock a buy up to 25.

Aircastle (NYSE: AYR) and Genesis Lease (NYSE: GLS) are both aircraft leasing companies and publicly traded partnerships, and both are holdings in the Personal Finance model portfolio. He notes, "As airlines continue their recovery and passenger volume rises, older planes must be replaced and new planes added to the fleets."

Both partnerships, he notes, are based in Ireland and lease to both passenger airlines and cargo companies around the world. He says, ""Aircastle and Genesis are excellent bets on the continued growth of air travel and pay dividends of around 6% and 8%, respectively."
