We have reached an odd situation with airlines now. The modern world requires airplanes to function, but they're so expensive to run that they are already optimised up to the eyeballs. Any little delays bump the whole schedule out of whack, plus they're cutting costs and services everywhere they can just to maintain an operating profit in one of the most competitive industries on the planet. There's no loyalty to speak of, so we all pick the cheapest flight we can get for where we need to go.
However, airlines are also businesses. They should, technically, have the right to refuse service to any person for any reason, from "I think you might be a danger to others" down to "I don't like that thing you said about us on Twitter".
And there's the conflict. Our world depends on airlines, so they're a necessity, and necessities should be rights, but they have the right to deny us their necessary service for arbitrary reasons. We need to fly, but we hate it, and if we say so, they can keep us from flying.
So what do we do? We need an airline that cannot deny us service for arbitrary reasons, only for operational ones. A not-for-profit airline. Well, providing necessary services where it is not profitable to do so should be one of the pillars of government. Perhaps this is a service the governments of tomorrow should consider investing in, along with education, public health care, roads and internet service.
