Pointed or sharp objects, like your Swiss Army knife, and dangerous products which are explosive or flammable, such as spray paint, flares and gasoline, are also not allowed. > > > What to wear on a flight: > > > - The aisles of an airplane aren't the place for a fashion parade. Don comfortable layers and go for shoes that are enclosed, flat and easy to pull on and off. > - The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-haul flights. Reduce the risks by staying hydrated, keeping your feet and legs moving and wearing compression socks to help improve your circulation. ### How to get through airport security fast when flying to St. Robert? > - Be sure to keep your ID and travel documents within easy reach.
