How does it compare on cost, though?? One of the great things about flying in Europe is the price, usually less than £50 a ticket, sometimes low as £5, it’s usually cheaper to fly than take Eurostar.
That's the thing of course. National airlines get bail out after bail out, pay zero taxes on fuel, have national and regional governments finance most of their on-ground infrastructure (airports), have their vehicle development also largely financed through governments, while railways need to keep their own pants up in every way. There is no fair competition of any kind, and I wish it was so!
