How do you avoid double slot costs when you adjust a route?
For example adding a techstop on one leg, but leaving either the arrival or departure time the same. When opening the route editor a techstop cannot be added. So a new route has to be opened. Now paying only for one new set of slots is ok, but it shows me slot costs for both airports.
When the new route is created and then the old one closed but with keeping the slots, are these then refunded? Or does the old route have to be closed (with keeping the slots) first and then the new, modified one opened?
