Do you have any tips for my flight to New Castle?
Depending on where you're coming from, your flight to New Castle could be completely painless or it could drag on forever. We've compiled some useful travel tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

  • A plane trip can be easy if you take the right stuff. 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?
It's all about being prepared. We've compiled some useful tips for a fuss-free trip through security. Look out New Castle, here you come:

  • 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. Make the whole process easier by removing them as your turn draws near.
  • Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online in no time.
  • Any liquids or gels, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other bulky shoes are usually subjected to additional screening.
  • Airlines won't allow any sharp items or pocket knives in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked luggage.
