Do you have any tips for my flight to Castle Rock?
Wherever you're jetting in from, flying can be a pleasurable experience if you've prepared well enough. We've put together a list of top travel tips that will help get your Castle Rock vacation started on the right foot. What to pack in your hand luggage:

  • First of all, put in your passport, official ID, credit cards and vital medications. Next, you'll want some extra in-flight entertainment to while away the hours. A juicy novel and a laptop crammed with your favourite movies are some wonderful options. If you plan to catch a few z's, a quality neck pillow and some earplugs will also be useful. Finally, leave some space for a toothbrush and some facial wipes to ensure you step off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your beloved Swiss Army knife, and dangerous products which are explosive or flammable, such as aerosol cans, spray paint and matches, are also restricted.

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in temperature by layering up, and pick flat, easy-to-remove footwear like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to Castle Rock?
A little pre-planning before you arrive at the airport will help make your trip to Castle Rock easy and painless. We've rounded up some useful tips for a swift journey through security:

  • First things first. Your passport and boarding pass will need to be shown to airport security. Have them close by so you don't hold up the line.
  • Next up, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items such as your belt, jacket and earphones will be required to go through the machine.
  • For just a few minutes, you'll need to unplug from technology. Your phone, tablet and any other electronic gadgets also need to be sent through the scanner.
  • Don't forget to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed on board and will be confiscated.
