No industry has crushed investor's dreams like the airline industry. Time after time, companies require immense amounts of capital and must contend with low profit margins. That’s not a winning recipe, but Rule Breakers analyst Sean Sun thinks he has found a winner in Allegiant Travel. Watch his thoughts in the video below:

How does Allegiant do it? How does it beat out Southwest (NYSE: LUV) to become what Sun calls “the best airline in the world”? Sun believes they’ve created a differentiation offering by going after leisure travelers and underserved routes. Allegiant provides direct routes in areas of high market demand with little competition, which is a winning formula that delivers industry-leading return on capital and revenue growth.

So forget about Southwest or legacy airlines like UAL (Nasdaq: UAUA) and Delta Air Lines (NYSE: DAL). The future of air travel belongs to Allegiant Air.
