That's a really horrible experience. I have never been on an airplane, however I can relate your experience in regards to the other forms of transportation. You certainly deserve praises for your comportment during these stressful times, but I think most people sometimes act that way as a result of the long boring flights. They eventually get anxious, bored, and stressed out- and although there is no excuse for their uncouth behavior- we must also bear in mind that everyone reacts differently to stress and anxiety.
