Really, it's useless. Planes aren't really worth it when you have plane crashes enabled, not counting the fact that an airport; isn't always the best transportation solution. It can't have as much capacity as a big and well-managed station. An 16-track through-station (for an example) is better than an intercontinental airport because planes load and unload slower.
Certainly. But they are a great way to get started and your money in order to build up the much more expensive rail infrastructure
@JustMoreMemes: You could simply forbid planes altogether by setting their allowed number to 0. Or make a NewGRF which disallows planes carrrying passengers.
Yeah, setting their allowed number to 0... but apparently he wants to keep them for goods, etc.
I agree having a good plane service is a good financial help and it saved me from bankruptcy a number of times while in a recession. How great planes can be ?
To be honest, planes are good only for long distances, like more than 256 tiles, when you're getting profitable trains. The modern trains, especially maglevs, beat planes on short distances, because they are cheaper and have more capacity in general. But when it's about getting to a city at the other end, better keep your planes, they become more efficient, especially if you timetable them correctly.
Also JustMoreMemes, while I sure don't accept the behaviour of the admin of having banned me with this message, I can clearly understand why he did this (It was like 3 years ago, and they unbanned me since), as you just don't block somebody's infrastructure - I think it goes for any player.
