Trying to book tickets from Madrid to Seville on RENFE site. The options I can see there differ significantly in price, depending on the service provider. AVE trains are generally more expensive, but I can at least book them.
There are two options I really want to book: Alvia or Intercity:
But when I try to book them I get this error: Tarifas no disponibles en el trayecto y fechas seleccionadas. Pruebe con otras fechas. Inc 3471 (F063)
In fact, I tried other dates, even next Monday or mid November, and I'm still getting the same error for any Alvia train.
Should I wait for tickets to be released? Or should I give up and book a ticket for an AVE train?
