While most of your ancestors probably never set foot on an airplane, let alone knew anything about frequent flyer miles, you can earn miles for researching your family tree. US Airways Dividend Miles members can earn up to 5,000 miles for joining Ancestry.com. Register for a six-month membership to search the U.S. records for $14.95 per month and earn 1,250 miles. Choose a 12-month membership for $12.95 per month and earn 2,500 miles.

Ancestry.com also allows members to search records from around the world. Register for a six-month membership to search international records for $26.95 per month and earn 2,500 miles. Choose a 12-month membership for $24.95 per month and earn 5,000 miles.

Although membership is based on a monthly fee, you will be billed in one payment after your introductory 14-day trial, so if you sign up for the $24.95 per month offer to earn 5,000 miles, you will be charged the full $299.40, so this isn’t a great deal if you are only looking to earn the miles and cancel the service.
