Duck,
Stop wasting your time with these guys. They wish they had 170s on their property. And before you guys start telling me the 170 belongs on mainline, I want you to go and ask 100 CAL pilots this question, "If you could have the 170 on property, will you take a seat?" I am going to go on a limb and tell you what the results will be. 100 No's and 0 Yes's. They will not leave their 73s and 75s. Good luck with that.
Oh one other thing, who would have thought that Delta would give up more scope? I love how people who do not work for CAL and try to tell everyone in the world that they will not give up scope. I am not saying they will, but you people need to stop telling me what someone else thinks.
