Miles & More is giving away 500 miles for those who log into their mobile app for the first time. The promo runs through September 30, 2017. Additionally, you can earn 500 miles for signing up for the Miles & More newsletter.

While not the most well-known airline loyalty program, Miles & More has some interesting opportunities for booking domestic flights on United and flights to and from Europe with their Mileage Bargains.

Watch out for the taxes and fees that are incurred on flights to and from Europe. If you book flights from Brazil or Hong Kong, those fees will be greatly reduced.

The Miles & More program includes airlines such as Lufthansa, Swiss Air, Austrian Airlines, LOT Polish Airlines, Brussels Airlines, and more.
