This is a fictional Crossair (McDonald's) livery for the FlyJSim 737 which is based on a special Crossair scheme. This livery features outlined doors and a the letter 'M' at the front. The registration is also based of a Crossair (McDonald's Livery) McDonnell Douglas MD-83. If anyone does spot any mistakes in this repaint just comment, I'll be happy to edit anything that isn't accurate!
Have a pleasant flight!
