Go for shoes that are easy to slip on and off, dress in loose, natural fibers and remember to bring a sweater in case you get cold in the cabin. > - You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To minimize your risk on board, drink plenty of water, consider wearing compression tights or socks and keep your legs and feet moving. ### How to get through airport security fast when flying to De Soto? > - Keep your passport and boarding pass within easy reach.
