1-Call Merryweather for air extraction, this will cost $1000, you can get that money by robbing a store.

2-Once the helicopter lands, kill the driver and steal the Maverick

3-I gained a 1 star wanted level, so the army was looking for me, I didnt gain 4 stars until a car spotted me (MAKE SURE YOU LAND BESIDE A JET!!)

4- Steal the jet and lose the wanted level, and voila, you got a jet.

Note:I know this is a crappy tutorial, but hey, I'm atleast trying to help

Or you can get a free helicopter from the helicopter base is on single player, where your helicopters go.
