Dec. 8, 2013 -- It was kind of a scary flight on US Airways earlier this month thanks to a passenger thought to be sick with tuberculosis. He ultimately tested negative for TB but it's a good reminder not to fly if not feeling well because you might infect others.

Oh, who am I kidding? We've all flown sick. Airline change fees are way too expensive for the luxury of retooling an itinerary simply because of a cold. But as long as sick people fly, is there any way for the rest of us to stay healthy?

Yes and no. There are things you need to worry about but also things you can do to protect yourself. And sometimes, you just have to kick back and hope for the best.
