Don't be predictable. Also as newporg said, when searching for enemies or when in a dog fight, turning to 3rd person will help you spot them much faster that you would in 1st. Switch to first and take the kill etc.
Fly around the out-skirts of the map. Make your mini map zoom out to the furthest extent. Search for Jets/Helicopters. If you do not see any of those then maybe Mobile AA, if none of those then go for a strafing run on a flag that is being captured.
