The truth is Uncle Phil and his cronies are more powerful than SE and his cronies.
Phil wants to go 10 years without a pilot contract. They have no desire to give 9E a fair and reasonable contract. No desire for an industry average contract. They want the airline to be paid far below industry average in all forms and fashions.
TA1 was designed to fail. They were glad it did. TA2 is being designed to fail also. After 6 years of stalling, their only options are to have TA's fail to buy them more time.
