Carl,
Effectively it is operable as a PWA.
Interestingly the Comair "commitment
letter" example was also signed by ALPA's President. I had never made the distinction that it was unusual for a President to sign a LOA. But you might be on to something here. This resonates with a report from an attorney (which I did not completely understand and I am not sure it matters).
This attorney states the President's signature is there because ALPA is serving as the vendor for alter-ego outsourcing using Pinnacle pilots. He also believes the contract is unenforceable due to a number of flaws, some of which include the non participation of the Delta pilots in the modifications to our pre existing PWA (he refers to us as the "fifth party.")
I'm not going to report his whole analysis of the mess since I am not even sure I completely grasp the concept and can't defend his position.
I don't have to understand how a fish decomposes to know this whole deal smells like low tide.
