If it happens systematically and in a way that effectively creates one big multilaterally maintained and honored private “no fly” list and a corresponding chilling effect? Absolutely. Otherwise, I’m afraid we’ll quickly have such a list for people exercising their legitimate EU flight compensation rights or anything else inconvenient for airlines.
Airlines should on the other hand be free to set their own restrictions on filming in their planes and publishing that material – clearly communicated at the time of booking. I’ve been on a flight with a Youtube “personality” just looking for drama with the airline, and even as a bystander I found it obnoxious (and I didn’t want to end up in that video myself).
If they did it independently, no. I don’t think it’s a travesty if someone pushes everyone to refuse to do business with him.
If the airlines passed names around, it’s effectively a worse NFL and, I think, should either be prohibited or run by a very transparent agency with clear challenge rules. No comment on how realistic the latter actually is.
If some idiot ends up blacklisted by enough airlines that air travel becomes impractical for them, tough shit. He can still travel by land or sea, and those methods of travel are also considered privileges.
Noone is entitled to means of travel beyond their own two feet, or a practical equivalent for the handicapped, in spaces they have a right to access.
If other airlines banned this flyer as well would that be a problem?
