This news story poses a very interesting question. A group of people who had used a toiletry item that had an odour other people found offensive were deboarded from a flight. That's the essence of it, but it's complicated by the fact that the complainers were white and the people they were complaining about were black.
An American judge, Oliver Wendell Holmes, said "The right to swing my fist ends where the other man's nose begins," and this story that shows that there's more than one way to assail a nose. There must be a line somewhere between someone turning up a nose at an unfamiliar odour, and hence at the person attached to it, versus someone truly experiencing physical distress on account of an offensive odour. It's not uncommon for an airline to refuse carriage to someone with extremely poor personal hygiene, and one often sees requests for people to avoid wearing extreme amounts of cologne in public places. But where is that line, and how do you draw it? If I sit next to you in an airplane I can likely smell your shampoo, your hair control products, your deodorant, whether you had garlic for lunch, and whether you're
sacred scared. I may find your smell distracting, but would you deserve to be kicked off a plane for it? Smelly is in the nose of the beholder.
I suspect that if the airline offered to accommodate the complaining passengers on a later flight, they may have suddenly found the odour more acceptable.
