Dry air relief
In-flight air is as dry as the Sahara. Flight Spray, from the makers of the popular No Jet-Lag, can keep nasal passages moist and help prevent colds, flu and sore throats that sometimes come with recycled airplane air and sitting near sneezing and coughing passengers.
Herbal ingredients — turmeric root and spearmint — smell nice and feel soothing in the nasal passages. The 1 oz. bottle is TSA-friendly but remind clients to take along a clear, one-quart plastic bag for faster security screening. $14.75. www.travelsmith.com
