When I consult the Eurail planner app, for example, Narbonne-Carcassonne on June 28, 2025, at 7:11 a.m., no reservation is required. However, when I add it to my trip, only when I enter the specific trip, a required reservation appears, starting at €1.70, even though I'm booking a TER. Should I make a reservation in these cases?
I bought a global pass.
