Lufthansa Miles & More members can earn double award miles when renting a Budget vehicle up until June 30.
The promotion is valid for online reservations and rentals at 3,400 participating Budget branches in Europe, North America, the Middle East and Africa.
It is only available for bookings made online and does not apply in Jordan, Norway or Poland.
To qualify, members must enter their Miles & More service card number when booking their rental car and present their card when collecting the vehicle.
The offer cannot be combined with other promotions.
Last year, Lufthansa upgraded Miles & More to offer members extra benefits including lounge and upgrade vouchers (see news, September 2014).
