Grab a fighter and just loiter over the battlefield, anytime the dipshit comes in, shoot them down. Usually after 3rd or 4th one they stop.
Get good at using flak. If theyr are suicide bombing, they usually just fly straight in, so one one tap is all you need.
And for mass pankakke enjoyers - if they crash without being hit by anything, give them a 1m timeout for next plane spawn…if they crash that one - 2m - next one - 4m, etc
