Oh wow... I never knew that there are others like me out there!

As for plane trips, I tend to freak out if I think someone near me might be ill. Usually, I sit by the window and my hubby sits next to the other person(it doesn't bother him).

I've flown overseas about 10x and in the states 3x and I've never seen or heard it ever (*knocking on wood*) so I don't think it's quite as common of an experience as you might expect.
