On Your Next Flight, Are You Looking for Comfort and Space? The JSX Airlines BUR Terminal offers a very unique seating experience. The plane has comfy, laid-back seating with plenty of legroom and leather-trimmed seats. There are no middle seats. Even on a brief flight, I valued the calm cabin and the feeling of privacy. Every seat had a fresh, comfortable, and well-considered feel. To be honest, it's among the most comfortable flights I've ever been on, especially considering how practical and effective the service is.
