After the Guggenheim airline exchange traded fund was grounded back in 2013, investment interest for airliners soared in 2014, and now ETF Series Solutions, a white label ETF service provider, is bringing back the sub-sector theme.

According to a recent Securities and Exchange Commission exemptive relief filing, ETF Series Solution and U.S. Global Investors, Inc. are working on the U.S. Global Jets ETF (NasdaqGM: JETS). JETS will have a 0.6% expense ratio.

The new Jets ETF will try to reflect the performance of the U.S. Global Jets Index, which is comprised of U.S. and international passenger airline companies and aircraft manufacturers listed in developed and emerging market countries. The underlying index will hold between 25 and 40 airline companies, weight components by their square root average daily dollar volume traded over the past three months and rebalance quarterly.

Airline stocks were among the best performing areas of the market last year, bolstered by falling oil prices and an improving economy. For instance, Southwest Airlines (NYSE: LUV) surged about 125% in 2014 and the Bloomberg U.S. Airlines Index rose 81.3 percent in 2014.

The industry is expected to keep soaring in 2015 as mergers, falling jet fuel prices and increased flight demand will keep airliners flying high.
