I have a few likes and dislikes.

Best - sorry, I like HP's look. It's different, what with the southwestern look and all and I have always loved the AW logo. Also like UA's new livery, hated the gray business suit pinstripe look. I also like Alohas livery with the bird of paradise on the tail.

Worst - NW's new livery. BORING! And I also dislike Delta's tail design, looks like a wrinkled piece of silk or something.

Needs a new look - AMERICAN!!! Come on AA, let's think about an updAAte!

I'm very much into logos and the domestic ones I like are HP's, CO, NW (before they changed it - they eliminated the stylized NW), and UA. Not too big on the airlines just using their name as a logo, like Frontier and jetBlue.
