When your ally has captured the flag, fly very close to the carrier. If you press 'E' at the right time, he can get into the plane and then just fly him back.

Invincible to bots
On the map Berlin if you don't want to be seen by bots simply go behind the fence by the river and you can kill all bots you want.
Kamikaze Car
A very VERY effective way of clearing enemy forces is by creating a Kamikaze Car. When you spawn, become an engineer, then using the Axis' jeeps, put all of your dynamite in the back seat of the jeep, (it will stay there while your driving, unless the car flips or you go up on down a steep incline) and drive it straight into the midst of the enemy forces. They will shoot the car and it will blow up with the added power of 4 or more sticks of dynamite, sometimes killing over 10 people.
Note: DO NOT use mines, once you start driving, they will blow up.
This only works properly will the Axis' jeeps, because they have large back seats and doors on them, if choose to Kamikaze in an Allied jeep the dynamite usually gets thrown out the doors.
Kill bots that aren't enemies
Hit tilde (~) then type: aiCheats.code Thomas.Skoldenborg.
Parachute Drop
When playing a LAN or Internet game, get into an airplane and instruct your friends to get onto the plane's wings. Get them to Crouch down, hold down the walk button and slowly walk forward when the plane is in motion, so that they don't fall off. Fly them over the enemy's territory, or more effectively, a crucial control point and tell them to let go of the buttons, and press jump (so that they don't hit the back wings) then parachute down to the ground safely and engage. Your friends can also attack shortly after putting their parachute up, so get them all to drop their grenades on the enemy, clearing their landing point.
This tactic is very effective at flanking or surrounding the enemy.
