This is your statement.

During the contract 2000 negotiations Delta settled their contract with a new level of wages and benefits which set a new bar for industry leading contract and was totally unexpected by the UAL Management.

Contract 2000 at Delta was signed well after UAL signed their contract. If you are speaking of the LOA on pay for the 737-800 that happened 2 years earlier. It was not a contract. It was one item on pay for new equipment.
