And almost always on time. And won't get cancelled as often...

People like flying because unlike railways services, it's a method of transport you can actually rely on.

Spanish high speed rail is incredibly reliable and normally on time. Not really a concern.

I don't know how it in Spain (but I heard their rail system is good), but in my country it's the opposite. Trains sometimes have small-ish delays of 5-60 minutes, but longer delays are rare and there are usually other trains running the same route, so you can easily switch (for free if it's the same company). I've never experienced a cancelled train.

With airplane, you often get these small delays as well, but there's also the risk of a very long delay. I had the pleasure of waiting 12 hours for a (connecting) 50 minute flight.

There have been summers in the US when "almost always on time" was a real stretch.

To clarify, I was talking specifically about domestic flights within EU countries. Here in Germany you're often paying about double for a train ticket, even if you book early.

Yeah, the plane is too cheap, that's a problem.
