You must receive the HM Fly through the adventure and after beating a certain number of gym leaders you can teach it to your Pokemon and once you teach it to your Pokemon, select it out of your party, and one of the options should be Fly.

Are you a noob!? All you have to do is teach the move fly to a Pokemon and then go to the Pokemon selection screen and select the Pokemon that knows fly and select fly under summary. EASY!

Once you teach a bird type Pokémon fly, you go ahead and click into Pokémon near bag. Finally you click the Pokémon who knows fly and there will be the option fly. The Pokémon can fly you to any place you have already been.
