I might prefer the RJ. Hell I might prefer a Dash 8. To each his own.

A domestic only 777 category... man I am there! Of course depending on what number I'd be.

But as to the 1:1 ratio between 777s and CRJ900s, I think it should be more simple than that.

Buy whatever you freaking need. You want 360+ 50 seaters? 255+ 70-76 seaters, fine have at it.

We'll fly it all.

In the interim:

Plan A will be SWA or RAH scope.
Plan B is significant gains.
Plan C is a new union.
