[Fairies] How do fairies fly standing up?

Their wings are on their backs, so if they just push air down the fairies would fall over. And they tend to have butterfly wings, which shouldn't even be getting lift from that angle. Do the ones with non-butterfly insect wings also push back with the lower wings and forward with the upper wings to provide torque? Why not just fly horizontally? It seems so much easier.

Fairy magic.

No seriously, it's just fairy magic. 

Fairies don't have much in the way of a physical form, they're more magic mixed with flower petals than living creatures. 

They barely exist in the same realm at mortals and so everything about them runs on fairy magic.
