Every week, every alliance member receives a set of destinations and a number of flights that should be completed during the week. When you finish all the flights to a destination, your alliance gets one point. Each member of the alliance can contribute up to 3 points by completing all the flights in 3 destinations. The flights only get counted in the weekly task when you have a stable Internet connection.
If all the alliance members manage to get a certain task percentage during the week, they receive a reward. The reward is different for a 10%, 30%, 50%, 70%, and 100% completion rate. Each reward includes a set number of reputation points. Completing the weekly tasks is the only source of reputation points now, as they are no longer given for alliance ratings.
When a player joins the alliance during the week, they can participate in the alliance tasks starting from the next week only.
Once a week, you can change a destination to a different one for free, but you will lose all the progress you've made at this destination. Every new change during the same week will cost you 20 Airport cash.
