US Airways Dividend Miles is offering 1000 miles for new signups. Usually these offers require some sort of flight activity before earning bonus miles. This one gives you the miles just for joining. So a good chance to join if you aren’t already a member.

For a limited time, enroll in Dividend Miles online and receive 1,000 bonus miles. That’s right, all you have to do is sign up and we’ll automatically credit 1,000 miles to your account. The miles don’t count toward Preferred status, and you can’t combine this enrollment bonus with any other offers. Enrollments must be made on usairways.com and only one bonus is permitted per individual.
