Itinerary

The itinerary allow you to make a list of 5 cities/slots that you can fly to without going to the Possible Routes page.

All you need to do is click the icon under each aircraft (you can see it only when your aircraft is on the ground) and pick any 5 slots (from your private ones or alliance slots) you want.

After that each time you go to the Routes Information page and you have an aircraft on the ground, you will see a drop down menu with the list of the 5 cities/slots you picked.

Choosing one of the cities will automatically send you aircraft to this city without asking for approval.
