Your Legion Flight Master's Whistle Works in BfA

I think more people should be aware of this, so here's a Blue Tag :D

Once you unlock World Quests in Battle for Azeroth the Flight Masters Whistle will be upgraded to work in Kul Tiras and Zandalar.

If for some reason you misplaced, lost or destroyed this fine whistle, you can get a fresh one by speaking to Halford Wyrmbane in Boralus(Alliance) or Nathanos Blightcaller in Dazar'alor (Horde) on your boat.

Happy whistling!
