Sign up for the Lufthansa Premier Miles & More World MasterCard and get 20,000 award miles after your first purchase or balance transfer. Then, earn up to 15,000 miles with balance transfers in the first 30 days! You'll earn 1 mile per $1 transfer. Miles can be used towards Lufthansa flights as well as Star Alliance partners, like United and US Airways (a domestic roundtrip flight starts at only 25,000 miles). You'll also earn 2x award miles on airline partner ticket purchases, and 1x award miles on all other purchases. Better yet, you'll get a complimentary partner ticket after first use of your account. There's a $79 annual fee, but it's waived for SEN and HON Circle Members and a 0% APR for 12 months.
