Hi! We are trying to reserve seats in May from Prague to Munich and are seeing that resverving seats is optional however are being given this message additionally:
“No price results were found. Pass holder reservations may be sold out for this connection, but there are other ways to check for available seats—more info below our timetable.”
Does this mean the train is sold out? We are quite confused. Is there another way we could still reserve seats or will we be okay without a reservation?
