@crescent moon @BrianIsFlyin @A.Sampeak and @Navigata07 - I do the same. I have 3 starred all heli destinations, and got 1 each of any heli related buildings. Now I use training flights to hit the flight numbers for the daily missions, and for a head start I send all three heli's off at night so I have 3 flights counted for the morning. That's it - they have no further use.
