One thing I can offer -- and I am sure there is a more holistic way to handle this, but anytime you fly or go in for surgery or anything, take a small amount of antibiotic ointment -- Bactroban, which requires a prescription, is the best, I was told - and put it on a q-tip and lightly coat the inside of your nose. This keeps any horrid germs from entering a dry and perhaps cracked nose interior where germs would love to set up shop.

Besides that, I remember seeing some natural remedies / preventatives on another post. I will look for it and post it here.
