I too rarely get sick and I'm on an airplane at least once a month. This bug is scary - a lot of my friends in Negril have caught it - and they have contact with tourists all the time who have brought it with them from farrin either from the plane or from where ever. I could never see myself wearing a mask though.
I make sure my immune system stays in good shape - I eat well and will occasionally dose up on airborne starting 4-5 days before I fly.
LeeAnne - I'd heard of that too. I also just heard these two nifty facts:
1. Don't overblow your nose - the mucus in there protects the germies from getting in
2. Eyeballs are huge receptors of all things environmental - incuding bugs.
Everyone stay healthy! This flu that's going around is a real bitch.
