7 for 7 pretty much summed it up. You pays your money, you takes your chances.
Regardless, there will be movement at envoy. How much and how fast is up to AA's hiring numbers and envoy's willingness to let the pilots flow in matching proportion. We've been given a lot of different numbers over the last several months, our union, ENY management and AA management have all put information out. We'll have to see which one turns out to be true.
All that said, I'm not too familiar with the restrictions incurred when accepting the pipeline agreement. If ENY turns out to not be the place you want to be, keep your options open and apply out as soon as the contract allows you to leave without penalty.
