I keep my Alaska branded Visa, because part of the annual renewal is a companion ticket good with any other fare for just $50...although after many years, they're bumping that to $99 for next time. Still, $99 extra to go with a friend to Hawaii or Mexico is nothing to sneeze at.

I am however, very tempted by the Marriott Visa. I've always had easy redemptions, and its nice to end a long trip in a higher end property.

Do me a favor. Don't talk to me about anything you can't spell.
