We are planning a family trip to Austria in December, and were hoping to take a nightjet route from Vienna to Amsterdam to catch our return flight. It looks like the December+ routes have recently become available on the OBB website, but for whatever reason the one weekend we want to travel the nightjet routes are listed, but still showing "Ticket not available".
Does anyone have experience to know what this means? Do we just need to be more patient, or should we look at arranging alternate transportation? I'm comforted that the route is at least listed, but given that all of the other weekends have tickets available it makes me nervous to keep waiting while our other options may disappear during the wait time.
I know nobody will be able to give a completely accurate answer, but I'm curious if others have experience in this area that might be able to calm my travel planning anxiety!
