I used to work at Mesa. I was originally hired with Liberty Express before the Alpa contract. All the san juanees I flew with were competent. They were better than most on systems knowledge. Overall though they didn't have the big picture when it came to staying ahead of the aircraft and situational awareness. If everything was going as planned they usually did great. If things went awry then their inexperience showed. Like everyone else though doing 4-8 legs a day, they caught on quickly. After about 3-6 months you couldn't tell the difference between a san juanee and anybody else hired off the street.
