one key dismount / mount / flying mount macro will help you save some action bars for other things
this macro will swap between flying and normal month in flyable or not flyable places (also will dismount you if mounted that will come handy for farm and attacking enemy in the air)
example :Code:/dismount /cast [flyable] "fly mount here" ; "normal mount here"
Code:/dismount /cast [flyable] Winged Steed of the Ebon Blade ; Acherus Deathcharger
