No. Imagine then your ballon pops and your pokemon goes straight to the ground and all it's blood splashes all over the place. Not good for a pokemon game.
They let Megazard X in Sky Battles, even though it loses its Flying-type. I don't think balloon popping would be that big a deal.
Isn't that because Charizard itself is allowed? It's a flying type and has to mega evolve to become Charizard X in the first place.
That was my point. That losing Flying-type/Levitate doesn't make a Pokémon fall to the ground and die.
Air Balloon makes them float but doesn't give them Flying Type or the Levitate ability. As Air Balloon isn't registered on the Pokemon into a battle starts while Flying Type and Levitate are always registered upon a Pokemon.
