Would you board an airplane knowing you had the flu? Would you worry about possibly infecting other passengers or airline crew? The decision whether or not to fly when you're sick is complicated because it's influenced by a number of factors.

With a little foresight, and by following these simple guidelines, you'll be better able to stay safe and healthy, no matter your destination this busy holiday season -- whether you're in India or somewhere much closer to home.
