My problem concerns airports...How do you get them to develop? 

 
You need a way bigger zone than 4x4.  You also need to make sure 
there's no tall buildings near it. 

~Another adds...

You need at least 6x4 blocks (tiles) of which all must be covered 
with power lines. Once some buildings have been built then demolish
the remaining power lines else the builder won't build !  Stick some 
roads to commercial buildings for extra profit !
