Best Western Germany are celebrating their 10th birthday by giving you 1,000 Miles&More miles simply by registering for Birthday Miles!
Register here with your Miles & More number and your Best Western Rewards number (use Chrome's in-built translate for best results in English).
It doesn't state that only German accounts are eligible so it's worth a try. I have UK Best Western and Miles&More accounts and upon registering received this positive message:
"Thank you for registering! We have received your registration and will credit your birthday miles on the specified Miles & More member account" 🙂
Terms and Conditions
The Birthday Miles will be awarded only once and only after correct, prior registration. For the correct specification of the Miles & More Miles & More membership number the member's responsibility. Miles will be awarded only to the owner of the Miles & More service card, which is qualified within the Best Western Rewards Birthday campaign for it.
