Bruce York, the guy that Enegma mentioned, is the Director of ALPA's Representation Department (ie. one of the head attorneys). If he and his department have already looked at it, as Enegma said, then you can trust their judgment.
Pardon the ignorance, but what is the purpose of the "status quo" clause? It apparently has no "teeth".
If a base was economical before negotiations - why isn't it economical during negotiations? In this regard, the clause would have purpose - no major [economical] changes during negotiations!
