No, but you can check yourself. Flying in Europe is cheaper than train or bus. Not sure if there are Ryanair style cheap airlines in the US or other parts of the world.
Isn't this trading convenience (like flying stand by or at odd hours or dates)?
My guess is if flights priced in externalities they could not be cheaper than alternatives like trains. (Unless they're leaning on whales like first class to subsidize cheaper seats.)
Indeed. In particular, the rail ticket I bought at the destination airport was about twice the price of the flight, even though it was a much shorter journey.
