Just Cause 3 How to Fast Travel and Use Flares
HOW TO FAST TRAVEL
The Fast Travel Feature will not be available from the start. You first have to liberate provinces and complete the first few story missions.
Once you have progressed enough (not far into the game), you will unlock the mission “Friends Like These…”. After completing this short mission you will be introduced to the Fast Travel Feature, which lets you go to any discovered settlement.
