I flew JetSuiteX, now known as JSX, home from Las Vegas to Burbank, which turned out to be a pleasant onboard experience, though not without some disappointment on the ground.
While most US carriers operate under 14 CFR Part 121 (a classification for regularly-scheduled air carriers), JSX operates under 14 CFR Part 135 (a classification primarily for commuter and on-demand operations).
This is what allows JSX to offer a quasi-private jet experience and use pilots older than 65 (who still must pass the same rigorous health requirements as their younger counterparts) or have flown less than 1,500 hours.
A great solo travel tip spotted this week on Live and Let's Fly.
