You choose it whilst you are in the menu screens,before you fly you'll get a choice of 'Player plane',this gives you the choice to choose the skin you want to fly in during the flight you have chosen.
Re ATAG,I'm not 100% sure but I think only you will be seeing the skin,the other players will only see a default skin,but I'm not sure on that.
I'm sure they'll be someone who'll correct me if I'm wrong.
