The JCBA was never the vehicle for fixing all of that. It was defined by the MOU and limited by the conditions of the arbitration.
Voting No in 2012 got us the 1113 Term Sheet
It was the operation disintegrating that brought about LBFO2 and the 2012 CBA, then CLA, then MOU, then MTA, now JCBA
Voting No gets us arb, and Best Case, the MTA, possibly early openers in 2017( unless the AAG Board decides to "give" is the "deal" again...) and a Section 6 process constrained by the RLA and beginning with 2-3 years of talks about Parking and Passports before they even begin to discuss TheBigTicketItems.
There is a path to better, but it is not "Just Say No"
JMO, of course, validated by history
