I don't mind flying; I've done it many many times. The only issue is that a few times when the airplane was landing, I couldn't release the pressure buildup in my head and got extremely painful explosive head-splitting headaches. You know how your ears get popped and then they're supposed to unpop when you open your mouth or swallow ^_^; well when my nose is runny or stuffy on the airplane, I have a really hard time unpopping my ears and keeping them unpopped. So it builds up and leads to the extremely painful explosive head-splitting headaches. But the majority of flights have been fine.
