Getting the jet gets to be a pretty simple thing after a while, almost boring.
I'd prefer to drive than parachute.
Use whatever car, don't worry about car armour - just a vest, drive in from the far side (where the tower is) on whatever gate entrance side, take a left turn and optionally turn left then right or keep going straight.
Drive up to the end of the runway and bring all the cars chasing you up there, drive down the runway while looking at where the jets are to see if anyone is near them, find an abandoned one - take it and pull back. (Don't stop the car when driving, as police helicopters will spawn and be a PITA.)
Drive over the bridge, turn into the parking lot, bring all the troops following you on a chase around the runway until you find a plane, take it.
Stay away from the hangers as the tanks are usually there.
The jets i take are usually near the runway, there's 2 or 3 but sometimes a guy is there so either kill him or move to the next one.
Just distract the trucks/cars enough to bring them away from the jets.
