HI. My mum has had 2 brain tumors; one when i was two and once in the past 12 months. She is having seizures frequently and I am a bit worried about her safty when flying. My mum and I are flying to Denmark in December and my dad is coming a few weeks later, but since on the first flight, we are alone, I was wondering if there were any health risks. I would also really like to know what i can do to help her if she does have a seizure or something while I am alone with her.
