Best physical flying delta pokemon?

Hello there!, I’m wodering on what’s the best physical flying type in-game? I want it to learn fly, and also be useful in battle

later in the game there is a side quest where you can get a fly replacement

I’m still in the early game lol, and i really want to fly where ever i want to without using the taxi

oh, it seems I’ve misunderstood, they’re actually key items now instead of moves you need to learn
