Mesa historic block times are called segment times.
Those segment times are the six month historic average of that leg. If you push out and have to taxi for a four hour tour of LGA and then fly to PHL. You'll only get the 1.0 segment credit and not the five hours it will take you to actually perform the trip.
The Mesa people I know have one goal - fix it or burn it down. They are gathering the kindling now.
JO is setting up the China deal as a whipsaw. He's going to be moving CRJ's to China and establish flying there. Rumor has it that Mesa could lose a codeshare by November. In all honesty, that would probably "right-size" them for what they are currently undertaking.
Either way - Friends don't let friends fly for JO....at least not with this contract.....
I spent 9 years and 9 months at Mesa. The conditions they are currently working under far surpass the shizzit I experienced.
Godspeed to the YV crews and get a great contract...!!!
