Thanks for all the responses, though this was certainly my favorite

I am very much looking forward to not getting upgraded on my transcons.
As Plat on Delta I was 12/12 last year. I may stick with DL for NYC-SFO/LAX.
From what I'm hearing EWR-IAH-SFO/LAX may be better shot at the upgrade, though I don't think I can stomach the layover.
Thanks everyone.
