Furthermore, Wonderbolts Academy may have been the first time Rarity had the spell cast on her, but her friends already had it cast on them in Sonic Rainboom.

Also, when Twilight describes the spell she used to give Rarity wings, she notes that it is only for three days. But when she brings up the cloud-walking spell, she makes no mention of it wearing off at any point.
