Next, you'll need some in-flight entertainment to while away the time. A thrilling novel and a phone filled with your favourite movies are some great options. If you plan to catch more than just forty winks, a neck pillow and a pair of earplugs will also be useful. Finally, make room for a toothbrush and some deodorant to ensure you step off the plane feeling fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items can differ between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like tools, metal cutlery, fuels and bleaching agents. Sporting equipment like ice skates, and items that could injure passengers, such as firearms and swords, are also banned from the cabin. > > > What to wear on a flight: > > > - The aisles of a plane are no place for a fashion parade. Don comfortable layers and choose shoes that are flat, enclosed and easy to slip on and off. > - Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Diez? > - First things first. Your passport and boarding pass will need to be presented to airport security. Have them easily accessible to avoid fumbling around for them. > - After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items like your belt, coat and earphones will be required to go through the machine. > - Electronic devices like phones and laptops will also have to go on a tray to be scanned. No need to worry though, you'll be back online before you know it. > - Any liquids or gels, such as shampoo or hand cream, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag. > - Choosing your footwear wisely can save you a few precious minutes. Boots are often required to be removed and X-rayed separately. Slip-on sneakers are usually not. > - Airlines won't allow any pocket knives or other sharp items in your carry-on luggage. If you must bring these kinds of items, pack them safely in your checked luggage. ## Book with confidence # Expedia flights to Diez Searching for cheap flights to Diez?
