Let me key you in on a little secret. Unions and contracts evolve. When we negotiated code share and scope in a previous life we had no idea the extent it would grow. Pilots saw money, the airline saw potential.
Today, unions have learned from their mistake and trying their very best to reign in some of the scope and code sharing.
That is why we are fighting so hard at Jetblue to limit or even prevent this. We have learned from the mistakes of our peers.
