Today I arrived in Madrid with the plan to continue on an ALVIA train to Santiago de Compostela tomorrow. I had called Renfe to make a pre-reservation by phone yesterday, and today, at the station in Madrid, I wanted to pay for and pick up my reservation.
Unfortunately I ran into a problem. The Renfe officer at the counter could find my reservation alright (using the reservation number starting with L followed by numbers). But since the reservation was on Elige Confort (apparently equivalent to first class on this train) and I have a second class Interrail pass, he said there was no way I could use this reservation. There was apparently also no way for me to pay a surcharge to the ticket. This was possible for me on my Renfe-SNCF ride from. Marseille to Madrid (there were only first class tickets left but I was happy to pay extra to get on the train).
My question is, if its really not possible to buy a first class ticket on a Renfe ALVIA train when there are no other tickets left and I’m ready to pay an extra price?
Wondering if anyone had the same issue/question :)
