Just because they're close to having what's called a TENTATIVE AGREEMENT (TA) doesn't mean they're out of the water. They union will probably, once the TA
is signed, present the TA
to the rank and file pilot group for their perusal and then they get to vote. Majority vote will pass the TA
and it will be implemented.
Point being, this deal still has to make it through the voting hands of all the people who will again, take one for the team.
