In defense of Mesa, they have been nothing but courteous and professional when I have ridden their planes. I know they have a bad rep, but it is not entirely the pilots' fault that they have a malevolent dictator for a boss.

I ask Mesa for rides all the time, but I would never ask GJ for a ride because I would never given them a ride.

Check the tail number before you walk down that jetway.

Oh, and the mainline guys very often know exactly what is going on with GJ. Some don't, but most do.
