Aren't there rumors of Mesa picking up 50 seaters? And by massive, you mean being the 3rd smallest regional?

I still will upgrade faster and make a LOT more money in 3 years at Mesa than any one in the same boat.

In case you haven't noticed, fuel is cheap. That makes the 50 seater economical again and, considering how cheap it would be lease with a massive surplus, TSA is in a good spot.
