They can also refuse to do business with you if you sue them? What is the point? By all means, suppress yourself to a regime of ultra large companies, if that makes you feel more safe – in this case you are merely paying protection money and the system you support is just like the mafia. In the EU they do take another route: They try to make grounds for a more competitive environment such that anti-consumer behaviour does not make sense. That is also why you don't see ultra large tech companies in the EU. And for consumer, that is a good thing, because it keeps companies in check. I can furthermore say that I indeed has flown with this airline since.
