I need a seat reservation for a trip on the 22th of june from Prague Hlavni Nadrazi to Bratislava Hlavna Stanica. In the app off Rail planner it says there is a train from 9:12-13:54. When I try to make a seat reservation on the official website of the train (I got this link from your website) I can not find this specific train journey. But when I try to book a different one from their site they keep asking me for a In Karta, but I do not know what this is and neither do I think I have it. I am one of the few students who won a DiscoverEU pass so I only need a reservation and not a ticket. Could you help me explain what a In Karta is so I can make a reservation.
Greetings Maxine
