Key levels
4th - Air Elemental Companion becomes Medium allowing you to ride it now.
(Enhanced link from substitution level allows you to ride a companion with no saddle and grants a +4 Ride bonus)
5th – Wild shape (no more fear of falling off mid flight if DM allows actions)
6th – Natural Spell
10th – Large Air Elemental Companion, can now power spells in whirlwind form
9th or 12th – Electricity damage that can stun and knock down enemies
Fly around on your Whirlwind ccing the battlefield, damaging, stunning and knocking down enemies when needed, using your Air Elemental to power storm spells when needed, and in if in melee (and have Knowledge Devotion) use Knowledge Planes, Aracana, or Nature to get a bonus to hit and damage vs constructs, dragons, magical beasts, outsiders, elementals, animals, giants, fey, monstrous humanoids, plants, and vermin … oh my
And possibly no side effect from Born of the Three Thunders if Wild Shaped as a plant grants immunity to being Dazed, if not it can still carry you and keep you from harm.
A fun storm build to play levels 1-20, if you like Halflings
