There isn't a single person who actually enjoys getting sick; unfortunately, traveling puts you at risk of catching something. Thankfully, there are many ways to help prevent that, and traveling with disinfectant wipes is one of them. Before even sitting in your seat, wipe everything down so your area will be clean before having to touch anything. This won't guarantee you won't get sick, but it is a great preventative measure.
The air on a plane is dry, and that, combined with many germs, is the perfect recipe for a cold, but disinfectant wipes can kill those germs before you touch them.
