no, that's not what i asked. what i asked was, should there be cheap short haul flights? i think no, because i think that flight prices should reflect all the costs including the environmental. short haul flights in particular involve a large amount of environmental damage proportional to their result, especially given that there are other travel options such as trains.
therefore no, i don't think it's your god-given right to have cheap short haul flights - preferably more than one a day - from cornwall to london. i think you should get the train.
