I'll start with four...
- FO pay rates (XJ rates well behind PCL TA'd rates)
- Health insurance (up to 15% salary equivalent for FO's with families)
- Dead Head pay (XJ=50% PCL=75%)
- Cancelation pay (XJ=trip guarantee PCL=leg guarantee)
So, let me get this straight... You're comparing a contract that you don't have, against XJs current contract, and without considering it's guaranteed SnapBack on Dec 1.
XJs contract is far from perfect, but it's in a completely different league than the POS contract you have now. There is nothing legally binding about the TA. At this point, it might as well never existed.
