This part of the health benefits seems like a can of worms favoring the company:

"If excise tax is unavoidable after mitigation is exhausted, plan costs will be reduced to remain below tax thresholds. Method to determine value of reduction is defined. Lost value to be returned to the pilots (in a tax efficient manner if possible)."

"Monthly contributions payable may not increase more than 10% per year."
If the contributions increase 10% per year, how much is that over the life of the contract?
