thicker but more pliant than horsehide
What I don't get is they were all going to Kentucky. How could they all turn down a free flight & $800. It's not like they had jobs to get back to.The mistake that United made was allowing passengers to board before the last passenger agreed to be reassigned. If the ticketing agent said no one boards unless we have all 4 passengers required, this would not have happened.
Also the other passengers were such jackasses. Instead of video taping, someone could have voluntarily deplaned. Age of social media at its worst.
