Hello all ;)
I imagine this is possible on German (DB) and Austrian (OBB) trains?
Why do you ask? I've noticed that on some lines the 1st class is often fully booked, whereas reservations in the 2nd class are "for sale".
Or do people travelling in 1st book more often than those in 2nd?
In a nutshell.
Thanks for your insights
J.-François ;)
