The event to play for this achievement is called "No Pain, No Plane Challenge". Its not misable if you play tour mode.
I was able to start this event after achieving 240 stars (5 star 48 songs on what ever difficulty and instrument). I also had 314,400 fans but I dont think that matters AS much.
Good luck!
EDIT: Dependent on what country you start from, you also need to have the 3 venue's open for that country.
