Most of these subsidies go to the traditional (and expensive) air carriers. Ryanair, which is the low cost king, is very famously anti-subsidy. Sure, there's some subsidization for airports and specific routes that governments care a lot about, but it's not like rail isn't subsidized either.

Rail is so inefficient that even cars are often cheaper. If you have 2 or more people in a group, especially if they're on a normal ticket, it's often cheaper to go by car than by train. A car can seat five, a train can seat hundreds and runs on efficient tracks instead of inefficient roads. It's all just utterly ridiculous.
