It certainly isn't a right. Do you want to take away the airlines ability to throw someone off the plane?
While I get we don't like it when it is "us" thrown off, we darn sure want them to throw off someone making threats or significantly disrupting the flight.
I didn't say anything of the sort. I was just amused by the word "privilege."
For many years US Airways and it's predecessors had a near monopoly on flights to and from Pittsburgh. And they treated their passengers like they should be "privileged" that US Airways would transport them to where they wanted to go. I had more than a few encounters with surly US Airways employees. One even involved airport security. And it seemed these unpleasant encounters always seemed to occur after the latest union contract was negotiated. The employees were angry that thru had to give concessions, but instead of sending their grievances to management, they would take out their anger on the passengers.
Well, US Airways lost its ability to be lords and masters over their passengers when Peoples Express and other cut-rate airlines sprang up in the 1980s. Got worse when Southwest, Jet Blue and others started cutting into the US Airways monopoly. Passengers were lured by the cheaper fares, of course, but they stayed with these newer airlines because these carriers knew the meaning of "customer service." Now, US Airways could have realized what was going on and maybe made changes to counter the inroads of these other carriers. But they didn't. US Airways continued to treat their passengers like dirt, then wondered why they were losing money and customers.
US Airways was eventually absorbed by American Airlines, but I have yet to fly with American. I sure hope American learned the lessons on customer service that US Airways did not.
