I did some flying already. According to the game stats, I flew for 45 minutes (real time presumably). I travelled 51 km by helicopter and 80 km by plane.
I read some recommendations regarding flying skill (see full post on reddit). It is however written for GTA V, not GTA: San andreas
If you've completed the flight school already and still aren't maxed, the second way to improve your flying attribute is by completing successful takeoffs and landings at each of the three airports.
I have no exp points in flying stat at all:
Can I gain exp points in flying before unlocking las Venturas and accessing the flight school?

You can if you want to Wait and enter the San Fierro field and fly the Maverick chopper.Takes an hour approx.
If you are Good at control then fly out to sea for the time you will Glitch the game. If you succeed you may get a pilot license. Now,you can access all the airport and you skills will improve.
