Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp or pointed objects, like your trusty pocket knife, and products which are explosive or flammable, such as flares, bleaching agents and fuels, are also banned. > > > What to wear on a flight: > > > - Your priority is to feel as comfortable as possible. Choose shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and don't forget to bring a jacket in case you get chilly in the cabin. > - The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights.
