1. JSX


Ready to live a luxurious life? This short-haul alternative to major airlines even has its own private terminals. The best part? You can arrive as soon as 20 minutes before your flight, and prices are often lower than those of major carriers. We found flights from Dallas to Denver hundreds of dollars cheaper than the same route on American Airlines. Unfortunately, flights are fairly limited and at harder-to-reach airports. From New York, for example, JSX only offers flights to Miami, and it departs from Westchester County Airport.
