Do you have any tips for my flight to New Castle?
If you're not prepared, air travel can be a real challenge. But don't hit the panic button just yet. Follow these useful tips and enjoy a trouble-free start to your holiday in New Castle. What to pack in your hand luggage:

  • The secret to having a worry-free travel experience is to pack in advance. So, let's start with the essentials: passport, official ID, bank cards and any vital medications. Next, bring on board items that'll help keep you busy, like some electronic gadgets or a thrilling novel. It's also smart to pack your chargers, a neck pillow and a pair of earphones. And of course, be sure to squeeze in toiletry items like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like a pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, flares and fuels, are also not allowed.

What to wear on a flight:

  • Your main priority is to be as comfortable as possible. Go for shoes that are easy to pull on and off, dress in loose, breathable clothing and don't forget to take a pullover in case it gets cold in the cabin.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To minimize your risk on board, drink plenty of water, consider wearing compression socks and move your legs and feet often.

How to get through airport security fast when flying to New Castle?
As savvy travellers know, the secret is to be well prepared before you arrive at security. That way, you'll be stepping onto that plane to New Castle in the blink of an eye. Follow these tips and get your trip off to a flying start:

  • Keep your passport and boarding pass easily accessible. They're the first items you'll be asked to show at security.
  • Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Personal belongings such as your jacket, belt and earphones need to go through the machine.
  • All your electronics, including your laptop and phone, are also required to be scanned separately.
  • Travelling with a new hand cream? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on baggage.
  • There's a chance you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Airlines will not allow any sharp items or pocket knives in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked luggage.
