First of all you'll need toiletry items, such as a toothbrush and some deodorant, a fresh set of clothes and a magazine or two. Next, find room in your bag for your electronic gadgets, chargers, medications and maybe a cosy neck pillow too. Lastly, remember to bring your passport, travel papers and some cash. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have sharp objects (like a knife or scissors) hiding in one of the compartments of your carry-on luggage. Other restricted items include explosive or flammable substances, like aerosols and matches, and gels and liquids in containers larger than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Comfort should be your main concern when choosing what to wear on your flight. Loose clothing is a wise choice, as are flat, enclosed shoes. > - Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clotting due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks. ### How to get through airport security fast when flying to New Castle? > - Your travel documents and passport will need to be shown to airport security. Have them easily accessible so you don't have to dig around for them. > - Your coat, belt, keys and other items in your pocket, like coins, will be required to go through the X-ray machine.
