I agree with all of your picks, except I think Alaska/Hawaiian will happen since so many carriers are getting crazy about adding Hawaii capacity. I could see DAL or AA/US then making a move for the combined carrier.

I think on the regional side things will really shrink. Skywest will be the biggest/best, RAH/pinnacle merge and become a smaller carrier with reductions from the AA/US merger. PSA/PDT/Eagle will gain more flying after the merger. Mesa will get bought by TSA/Compass.

The theme at regional level will be more 70+seaters ,less 50s
