If you’re heading to the legendary Oktoberfest in Munich, Lufthansa and foursquare have a special reward in store for you. Users who follow Lufthansa’s foursquare profile and check in to three Lufthansa-approved venues at Oktoberfest will receive the Oktoberfest badge.

Unlocking the badge entitles you to a €20 flight voucher good for a future Lufthansa flight. A redemption code will be emailed to you after unlocking the badge.

Lufthansa has also added tips to many of the Oktoberfest venues, like this one at Augustiner Zelt:

In the Augustiner Brewery the Oktoberfest beer is drawn from wooden barrels. The beer garden is really eye catching and very popular with the locals. The atmosphere is relaxed and family-friendly.

This year marks the 177th year for Oktoberfest in Munich. With roughly 6 million visitors every year, it’s the largest fair in the world. This year’s event starts Saturday and runs through October 4.

This is the first badge that’s exclusive to Germany, and one of only three available only outside the US and Canada. It’s a great way to recognize a major event like Oktoberfest. The discount from Lufthansa is just icing on the cake. We’ll likely see many more of these sponsored badges that are tied to specific events in the coming months as foursquare gains more mainstream acceptance and sponsors jump on the bandwagon.
