How to survive the flight to New Castle?
Depending on where you’re coming from, your flight to New Castle could be completely painless or it could go on forever. We’ve rounded up some handy hints that will help you start your next great adventure on a positive note.What to pack in your hand luggage:

  • The trick to having a hassle-free travel experience is to be prepared. First up, the essentials: passport, official ID, bank cards and daily medications. Next, bring on board items that’ll help keep you entertained, like some electronic devices or a magazine. It’s also smart to bring your chargers, a neck pillow and a pair of earplugs. Last but not least, be sure to pop in toiletries like a toothbrush, facial wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, blades, spray paint and fireworks. Sports equipment like baseball bats, and items that could harm other people, such as swords and guns, are also banned from the cabin.

What to wear on a flight:

  • Your aim here is to feel as comfortable as possible. Don layers of natural fibers and pack a cardigan in case it gets cool in the cabin. Pick a pair of well-fitting, flat shoes as it’s possible that your feet and ankles will swell during the journey. Leave the stilettos and chunky boots in your luggage.
  • Unfortunately, a risk of long-haul flights is developing DVT (deep vein thrombosis), a blood clotting condition caused by prolonged periods of inactivity. To prevent this from happening, take every opportunity to wander around the cabin. Compression tights and socks are another simple way to help reduce this risk.

How to get through airport security fast when flying to New Castle?
The answer is — be prepared. We’ve put together some useful tips for an easy trip through airport security. Watch out New Castle, here you come:

  • Your ID and travel documents will need to be inspected by airport security. Keep them handy so you don’t hold up the queue.
  • Time to strip down. Well sort of. Your belt, jacket, keys and other items in your pocket, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • All your electronic devices, including your laptop and phone, must also be scanned.
  • Remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a clever footwear choice as you’re less likely to be asked to remove them when going through security. Big boots and heavier-style shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won’t be allowed in the cabin.
