What does that matter? What a way to try and win a debate. It's like answering a question with "because". What defines a route? A line between two points flown by an aircraft. As I'm sure you've heard before, size doesn't necessarily matter, in this case. A piece of metal flown by a different company is hurtling through the air that results in job loss for another. I have nothing against Skywest, just trying to point out that they and every other regional has encroached on traditional mainline flying. And what defines mainline? A whole different discussion. If it's 70 seaters, Skywest is equally as guilty as RAH. But for you to "win", I'm sure it's aircraft that seat 71 or more...
