Travel tips are easy to find on the Internet, but some are better than others. Each week, we’ll bring you World Hum-approved travel tips from around the Web.

1) Take an early flight to minimize your risk of a delay. “[G]round delays are especially risky. That’s because pilots aren’t required to turn on the air supply until the plane is airborne. ‘As a result, everybody is basically recycling everybody else’s air,’ says Vance Fowler, M.D., assistant professor of infectious disease at Duke University Medical Center in Durham, North Carolina. A dramatic example of how rapidly illness can spread during a ground delay occurred in 1979, when a planeload of passengers in Homer, Alaska, was kept waiting for three hours. Almost 75 percent caught the flu, most likely from just one person.”—Self magazine

2) If your seatmate is sick, ask for a new seat. “There is a risk to having spray particles land on you (such as from a sneeze), since they can enter your body if you wipe that area of your skin on your nose or eyes...If you’re sitting next to someone who’s sick, you can ask to be reseated. Several airlines say that if there’s a seat available, they will reseat passengers upon request.”—The Wall Street Journal

3) Take echinacea. “To fight off cold and flu germs that might be lurking in the stale air of the jet cabin, start taking the herb echinacea several days before you leave. Three times a day, swallow a teaspoon of a 1:5 tincture made from Echinacea angustifolia root. Continue to take it regularly during your vacation and after you return home, but for no more than a total of 10 days.”—Andrew Weil, M.D., Prevention.com
