I have only had problems with flight once. I had been vomitting all morning (something I do occasionally docs aren't sure why) and was tired and dehydrated. I had a seizure while we were descending to land. Flight attendant was great and other than sleeping all the way home I was fine.

I was however asked to get a note from my neuro doc clearing me prior to flying which he did with no problem and airline was very gracious even offered to move my seat so I could be closer to attendants should I or my kids need anything.

Hope you have no prob's.
