Partially why I believe short haul city-to-city flights should have more taxes applied to them if viable alternatives exist. And ways to further ease the tax burdens more for the alternatives if possible. (A stick for using flights and carrot for alternatives) Penalising medium and long haul, and flights to minor towns or remote towns excluded of course as alternatives are rarely viable. And of course, alternatives can't immediately handle all the passenger load so scaled approaches are needed. Thinking more of the Paris-London, New York-Boston, etc. Seems it worked with Barcelona - Madrid already, which might be more due to convenience than price? Though don't think it will happen as the opposition will be too much, and making the taxes/fee rules work easily without complicated red tape will also doom it.
