Just noticed they revived it again. You can sign up now & they'll apply the bonus miles for all applicable flights since Jan 1. AND, you still get the 1,000 sign-up bonus miles.

I'm kind of bummed - now that I know we're going to Hawaii in December, I would have signed up for the highest tier.

I thought maybe I'd sign up again, but they already nixed that idea - there's wording in the offer you can only sign up once in a 12 month period.
