Please help! I am trying to book seat reservations with my eurail pass for a one way train ride from Paris Gare de Lyon to Nice Ville on June 28. The website says there are available seats for a 11:52 departure and a 18:37 arrival, with one change between the two trains.
This works out until the final “review order” stage where it tells me “one of the legs of your journey could not be booked”. It does don’t tell me which one and the same error occurs when i try later times.
What does this mean? Why would they allow me to go through with the seat reservation if one of the legs cant be booked? What can i do about this?
