1st drawback, it is over priced for what you get, 300 hours of flight time. 2nd, you have to go through college to get that 2 year degree at SJC. 3rd, it is a moral issue. Many pilots don't take too kindly to pilots that buy their way into the airline industry and not going through the regular way of gaining experience as a CFI for a few years. Especially guys changing careers who think they are too old and that it's ok to buy their way because they don' thave time to flight instruct and get experience. MPD definitely is buying your way since you only have 300 hours when you get the position at Mesa. Get ready to face some discrimination at places other than Mesa. 4th, and probably the most important, MESA is a very rough place to work at. The toilet paper you use to wipe your ass is worth more than the work contract for Mesa pilots. 5th, since at 300 hours it will take you a long time to get the minimums for a captain postion, you will be a FO with poverty wages longer.

My advice if you really want to though MPD and MESA and have 2year degree or better go through the PACE program not the primary. Go to your local school in Texas, get your 250 hours and a CFI rating cheap and instruct untill you have 500 hours and THEN do the PACE. That way you at least have some CFI experience and will have some dignity and self respect when facing future employers or fellow pilots. Although Pace is still considered buying your job. If you have time(18-30 months) then just do it the right way by instructing and EARNING the right to work at an airline. At 300 hours not only are you cheating the pax that rely on you for their lives but also you will be cheating yourself. I guarantee you that you will feel much better knowing that you earned your job rather than payed for it.
