Ive noticed on various youtube videos that you can have planes that you have added also at airport gates (if that makes sense) ive added various planes e.g. Easyjet,Thomson and can freely use them but how can I see an Easyjet plan at a gate instead of the standard 737 that is in the game.
One way is to install an add-on traffic program. I use MyTrafficX
Check for downloads from World of AI. you can select and choose real world liveries to replace default FSX liveries. It is really cool to see them on the ground at gates and to hear them on the ATC... Hope this helps.....
