How to design an airline livery? I see many airlines with beautiful liveries and I would like my airline to have such a beautiful livery but I don't know how to design one.
You need a software like photoshop, gimp, inkscape or another program to create or retouch graphics.
It is useful, also, a template of the aircraft you want to use.
And a good dose of creativity and graphical skill.
Have you tried the LOGO AND LIVERY (https://www.airwaysim.com/forum/index.php/topic,1487.0.html) thread?
