I had a terrible migraine in the middle of a flight once. The kind of migraine that makes one sick. I used the air sickness bag. Fortunately, the migraine had kept me from eating or drinking anything other than water, so it was nothing major. Unfortunately, one of the FA was awful to me (told me to hold on to the air sickness bag until the end of the flight as she was awfully busy and stalked off), at which point, I burst into tears. Another FA saw this, came over, asked me what was wrong. I told her I had a migraine. She brought me another blanket (I was shivering) and she said, "Oh honey, those are the worst! Here, let me take that for you," and discreetly took the bag from me. She brought me water, helped me get my medication out of my carry-on, and kept checking on me throughout the rest of the flight. A real AAngel.
