I am trying to book seat reservations on the Interrail website. The train I would like to book (a TGV Paris-Karlsruhe) is shown as “Not available”. At first I thought the train might be full, but then I also checked other dates (every day of the week) and other cities (Stockholm to Malmö, Hamburg to Karlsruhe or to Amsterdam, etc...)
Every single train I checked, regardless of time of day, date or city, is shown as “Not available”.
Is there anything wrong with the website or the interface, or am I missing something?
For information; I tried on both Chrome and Firefox, as well as the app. I have a valid mobile pass, bought at the end of June, which I will start using next week. I am booking only for myself.
Or perhaps I need to add the travel days to the mobile pass first?
I’m thankful for any help or tips!
