This news explains that, on the occasion of the celebration of its 25 years, RENFE sold the AVE tickets for € 25.
During the first round of this second day of tickets at 25 euros, the website of Renfe collapsed by the saturation of the number of visits.
This notary seems to me important, not only because they celebrated the 25 years of the company, but because normally the AVE tickets are usually more expensive. They usually cost around € 100.
I suppose it collapsed because it is often cheaper to buy a plane ticket than an AVE, but of course there are many cities in Spain that do not have an airport but if they have an AVE station, that's why I suppose people bought it To be able to go to see relatives, to make tourism, in short, what they wanted.
