Hi, I have problem to book seat reservaton in 2 trains. One of them is train going from Warszawa Centralna to Wien Hbf on july 4th and second one is going from Berlin Hbf to Warszawa Centralna on july 15th. In both of the them the reservation is required but inactive. The notification says:
‘’Prices unavailable
No price results were found for this connection. It is possible that all pass holder seats are sold out. Please try searching for another connection or check 'More information' and try other ways to book this seat reservation. If no pass holder seats are available anymore you need to buy a separate full fare ticket to board.’’
This notification shows on every available train these days. Is there any solution to this problem or I have to buy full fare ticket?
