By AIPAs own admission it won't effect existing fleets.
This is just voter maths. If the company wants someone to vote for a reduction in T&C's, the only way it can be done is
by doing it to somebody else.
To get the 50% +1 vote required to take a significant reduction in existing T&C for themselves, would be almost impossible, unless there were extenuating circumstances. Why would anyone ever agree to reduce his T&C? Existing T&C's can only ever be maintained or on a ratchet up under a majority voting system.
This is the trick, the bait & switch.
Maintain existing T&C for those who believe they won't have to ever face those conditions themselves.
Within a relatively short time existing fleets will shrink & be replaced. Then majority of those who voted to the lesser T&C's
for someone else will find themselves without a choice. There simply won't be enough seats on the lifeboat. Some will make it, but not many.
