To get the air out of your faucet before it gets to your hose, open the water faucet closest to the water meter to let the air out. Let it run for a few minutes. This releases trapped air from the pipes. Once the water runs smoothly from the faucet closest to your water meter, gradually reopen the outdoor faucet. One other thing to keep in mind is that faucets contain vacuum breakers (backflow prevention devices). These tend to cause air-like noises and are replaceable.
