To all users with airline wishes: 
Please check first if your desired airline is not already present in the game. Because we want to focus on airlines that are not yet in the game. 
But of course you can also ask existing airlines if planes or liveries are not yet in the game. 
All wishes for already existing airlines in game, have a low priority at the moment. I hope you can understand that 
The List with all real airlines in game you find here: List: All real airline mods for Airport CEO - #6 by modair 
If you know any airlines witch is/are not in game ,write us with airline name + aircrafts you want 
PS: It would also be nice if you could check beforehand if your desired airline is already on our to do list
here: Trello
Thanks for your understanding
