Just a tip.
If a random puts a bounty on you, drop what your doing and get up to the airfield in grand senora desert. Jump into chopper and fly for the day. If you must land use the skyscraper beside Iaa and fib buildings. Nice and safe there.
At low levels this should work fine. I guess in time as people level up the attack chopper might become available then the above tip will be useless.
Also, keep an eye on other players who might steal the fighter jet to nail you. Since it is harder online to steal jet it probably won't be an issue. Don't get timed out.
