Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Pointed or sharp objects, like your treasured Swiss Army knife, and products which are flammable or explosive, such as flares, chemicals agents and strong acids, are also prohibited. > > > What to wear on a flight: > > > - The goal here is to make yourself as comfortable as you can. Layer up in natural-fiber clothing and pack a jacket just in case you get chilly. Go for a pair of roomy, flat shoes as it's possible that your feet and ankles will swell during the journey. Leave the stilettos and heavy boots in your checked luggage. > - Unfortunately, a risk of long-haul flights is developing DVT (deep vein thrombosis), a blood clot condition caused by prolonged periods of inactivity. To prevent this from happening, make the most of every opportunity to walk around the cabin and stretch your legs.
