The description of the Fly spell reads:
The subject of a fly spell can charge but not run, and it cannot carry
aloft more weight than its maximum load, plus any armor it wears.
It is however difficult to figure how a character can charge without running.
What is the rationale behind this?

They're not saying you cannot run as in you cannot move faster than normal, but instead that you cannot use the Run action to move 4x your speed in one round. Double your speed is the limit (double move or Charge action). I'm not sure why the limitation -- probably for balance, because the speed given by Fly is faster than most natural movement speeds -- but maybe that helps make it make sense in your head more.
