The Northwest Visa comes with a 10,000 mile signup offer.

Northwest’s Fly Free Faster Second Chance bonus which runs through February 15th will award 5,000 miles for signing up for the Visa and completing two partner activities such as Mileage Mall purchases (minimum $25) or hotel stays or car rentals. Registration is required.

If you register by December 31st in the Mile-Zilla promotion and get the card by January 31st, you’ll get another 1,000 miles.

So your Northwest Visa signup by January 31st will net 16,000 miles. Plus you’re on your way to additional miles in the Mile-Zilla promotion with 40 credits. Ten more credits yields an additional 500 bonus miles, and can be earned by signing up for My NWA Info (5 points, but don’t do it until you’ve registered for Mile-Zilla!) and crediting another car or hotel stay to your Northwst account (5 points).
