Greetings, sorry for my english.
You can do it here, on forum: in the world you are playing in (choose it at bottom of the forum).
Also, AS Wiki gives you the opportunity to create a page about your airline and update it regularly.
Aditionally you can paste your own text into the box to enhance the information of your airline on your information-page. This is (for example) my information:
…
