"When it comes to strapping yourself into a jet fighter and fighting to the death, you reckon you can go toe-to-toe with the best. But how are your skills in an attack helicopter? Or a jetpack? You better be sure you're a jack of all trades before you step into this ring: up to four teams work their way through every flavor of aerial combat the skies of Los Santos have to offer, and the only thing that matters is your grand total."
"You picked up a couple of cheeky kills in a P-996 Lazer and dubbed yourself 'King of the Skies', but how are your skills in an attack helicopter? Can you duck and dodge in a Thruster? Well, Air Quota is here to put your claims of greatness to the test in a gigantic aerial fracas for up to 4 teams and 16 players. Work your way through every flavor of airborne combat the Los Santos skies have to offer the only way you know how - by blowing your opponents to bits with Missiles and Cannons."
The concept of the mode is essentially the same as Kill Quota, where the player starts with the strongest weapon and tries to reach a kill quota in order to switch to the next weapon, usually a weaker one. When the last weapon is reached, one kill to the opposing team(s) will win the round for that player. If a player commits suicide, they will lose a kill towards the quota.
However, unlike Kill Quota, it does not necessarily follow the "stronger to weaker" ordering. Instead, the ordering is based on the versatility and the capabilities of the aircraft, meaning each player starts with the most maneuverable aircraft with better weaponry and progresses up to the least versatile aircraft with the most basic weaponry.
