As it turns out it doesn’t actually cost that much on regular transit, there’s an AIRPORT SURCHARGE because it’s an “airport train”.
No wonder Americans don’t use public transit, even when the system exists it’s ridiculously difficult and expensive to use.
I want that in the Netherlands as well. Much smaller country, so less value for your money. But now you pay even more (€66) for a return ticket from the east border to the west border (Winterswijk - Scheveningen).
