Thank you for the train ticket tips last night @Sebastiaan If you could post them here as well that would be super handy.

I am now doubting myself, I will verify this before I post!

DSB doesn't seem to specifically address if you can stop halfway and then take the second leg of the journey later the same day. They do say it's a ticket for one trip between two stations: https://cdn.discordapp.com/attachments/1380098936349397032/1380109656940089384/image.png?ex=6842aec7&is=68415d47&hm=d48ec311890c7fa6bd45c4df35a99e654355b50ce53b2188a7d0bef3fcbbd1e7&

Yep, I just talked to them, you have an hour to change to a different train along your journey but if you're staying in Copenhagen for a few hours, then you need two tickets, one from Airport --> CPH and one from CPH --> Odense. I am confused because in The Netherlands they don't care how long you take. Sorry for the misinformation! 😅

Thank you both very much for clarifying.

Same in Belgium, they don't care either 😅
