That's right, they apologized to all the passengers who had to give up their seats -- simultaneously underscoring what a caring company they are and how not-a-big-deal it was that one of them ended up bleeding profusely from his face, repeating "I have to go home" and "Just kill me." The takeaway here is that it takes a big corporate conglomerate to admit when they're wrong, and United is happy to take responsibility for slight inconveniences when it's actually their fault. Furthermore, they're already working with authorities and "this passenger" to "address and resolve" the situation, so the rest of us should probably keep to ourselves, because it's none of our business and bad things happen to noses that get stuck where they don't belong.
Also, let's not forget that the guy who rudely insisted on staying in the seat he paid for is no saint. In fact, he's a doctor. A doctor who once was convicted of trading drugs for sex! So we should be thankful to United for predicting, before having any information, that he had a troubled past! Even if United is sometimes rough with their passengers, it's not like we're so perfect. In fact, all the passengers filming Monday's exchange may have been breaking the law just by recording video on the airplane.
