Lufthansa Group’s Brussels Airlines has launched the Loop loyalty program for travelers within its European network.

Through 2015, each euro spent, excluding airport taxes, will earn a customer six loyalty points that can be used toward future flight purchases. After Dec. 31, each euro spent will earn a customer three points. They can be cashed in after five round-trips or 5,000 points, and payment can be split between points and cash or credit. Points do not expire as long as the customer flies on Brussels once a year within Europe.
