How to survive the flight to Castle Point?
We've got the lowdown on how to make your journey as pain-free as possible. Follow our top tips and you'll be speeding through airport security and seeing the best of Castle Point in no time flat.What to pack in your hand luggage:

  • The secret to having an awesome flight experience is to pack ahead. Start with the essentials: passport, travel docs, cash and important medications. Next, take on board items that'll help while away those hours, like your laptop or a magazine. It's also smart to pack your chargers, a neck pillow and a pair of headphones. Last but not least, don't forget to pop in toiletries like a toothbrush, lip balm and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, blades, spray paint and fireworks. Sporting equipment like ice skates, and objects that could harm passengers, such as guns and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • Comfort really should be your main priority when selecting what to wear on board. Consider your footwear choice carefully too, as swelling of the feet and ankles are a common side effect of flying. Slightly roomy, flat shoes work well.
  • Most travelers are aware of DVT (deep vein thrombosis), a blood clot condition caused by long periods of sitting. There are plenty of ways to reduce your risk. Wear a pair of compression socks or tights, drink plenty of water and remember to keep your legs and feet moving. Wander up and down the aisles of the cabin or try out some simple stretches in your seat.

How to get through airport security fast when flying to Castle Point?
As seasoned travelers know, the secret is to be well prepared before you arrive at airport security. That way, you'll be hopping onto that plane to Castle Point in a flash. Follow these tips and get your trip off to a spectacular start:

  • Be sure to have your ID and travel documents close by. They're the first things you'll be asked to show at security.
  • Next up, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items like your belt, coat and headphones need to go through the machine.
  • All your electronic devices, including your tablet and phone, are also required to be separately scanned.
  • Want to bring along your favorite cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be required to remove them when going through security. Big boots and heavier-style shoes are usually subjected to additional screening.
  • Airlines won't allow any sharp or pointed objects in your carry-on baggage. If you need to bring these kinds of items, pack them safely in your checked baggage.
