Once you reach level 5 you will be able to create or join an alliance.
Alliances will bring you additional passengers through codesharing.
For each alliance member the chance of getting additional passengers increases.
All passengers through codeshare will be deducted a small amount that will go to the alliance, and helps determine the alliance value.
It is free to join an alliance, but subject to approval by the alliance admins.

To create an alliance will cost both cash and bonus points.

If you are a member of an alliance, your alliance name will appear on your profile and when posting on the boards.
