If it works the same way as last year, I took a AMS-DPS-MAD open jaw, and got globetrotter bonus miles for both DPS and MAD, two badges as they were in different themes, and the route launch bonus miles from AMS. Happy days
Edit: As a data point for this year, I flew into Oslo today on a ticket I bought several months before the launch of this year's promotion, but have the globetrotter bonus miles credited to my account already. So no waiting until the end of the theme period like last year.
