Not quite...if it were true, we'd probably be doing addt'l flying, not replacement flying - routes that can't support a 737 (when WN goes in, they take no prisoners with 8 non-stops to everywhere haha). It would be great in that you upgrade quick...but bittersweet nonetheless.
What a crazy world. We'll just have to wait and see. This is one of those times I can't help but be flabbergasted - plausible and insane at the same time, it just boggles my mind haha.
