How to survive the flight to Castle Rock?
If you're poorly prepared, airports and flying can be overwhelming. But there's no need to worry. Follow these tips and tricks and enjoy a worry-free start to your getaway in Castle Rock.What to pack in your hand luggage:

  • First things first, pack your passport, travel documents, cash and daily medications. Next, you'll want some entertainment to help pass the time. A thrilling novel and a laptop filled with your favorite movies are some fantastic options. If you intend to take a short nap, a quality neck pillow and a pair of noise-canceling headphones will also come in handy. Finally, leave space for a toothbrush and some deodorant so you'll step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, knives, spray paint and flares. Sports equipment like baseball bats, and items that could injure passengers, such as guns and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • The key to a comfortable flight is as simple as the clothes you wear. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin starts to cool down. Shoes like sandals and heels are best left for other occasions. Even though they may be your favorites, go for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
  • A condition called deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clotting due to poor circulation. Doing leg and foot exercises in your seat is a great way to prevent this from occurring. Wearing a good-quality pair of compression socks or tights can also help.

How to get through airport security fast when flying to Castle Rock?
Being organized before you arrive at the airport will help make your trip to Castle Rock a piece of cake. Here are some useful tips for a stress-free journey past security:

  • Your ID and travel documents will need to be shown to airport security. Keep them handy to avoid fumbling around for them.
  • Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • All electronic devices, including your phone and tablet, are also required to be scanned separately.
  • Remember to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
  • Choosing your footwear wisely can save you several minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Sharp items such as knives and scissors can't be taken on board. They'll be seized at security, so pack them safely away in your checked baggage.
