The United Boeing 787-8 would be a great new livery for the game. The 787-8 is part of the United fleet and does many long range routes. The 787-8 is one of my favorite planes, why because they are on the smaller side but they have a long range of travel which is super cool. There is not many American Airlines for the 787-8 so the United livery would be awesome!
