Investors are already well-aware that an upswing in commercial aviation is underway. Boeing (NYSE:BA) and Airbus are delivering more and more planes, and companies as diverse as General Electric (NYSE:GE), United Technologies (NYSE:UTX) and Alcoa (NYSE:AA) have been talked about for their exposure to the commercial aviation cycle. While plenty is written on these commercial aerospace plays and commercial airliners, the large airplane leasing companies don't get the same attention. With attractive financing terms, improving lease rates, and strengthening commercial airline trends, now may be the time to consider a name like AerCap (NYSE:AER).
