What response would you like?
Case 1: Your fault
Being drunk, or unruly, or nude, or hitting too hard on the stu, or talking about bombs, or sitting in the wrong section and refusing to move, etc...Then I commend the major corporation and also feel it is a shame that customers have to put up with such shameless other customers!
Case 2: Overbooked
Too many reasons and combinations to say.
Case 3: Airline employees drunk, disorderly, with a case for people "like you??". This case is quite unusual, but if it is the case then I suggest you go to court, or at least the FAA.
Again what kind of response did you expect to get??? Double posting for your benefit, not ours, is not too cool.
