How to survive the flight to Castle Danger?
Wherever you're coming from, flying can be a seamless experience if you've prepared well enough. We've made a list of essential travel tips that will get your Castle Danger vacation started on the right note.What to pack in your hand luggage:

  • It's simple --- first, pack in your passport, important documents, wallet and daily medications. Next, you'll need some entertainment to help pass the time. A thrilling book and a laptop crammed with your favorite movies are some terrific options. If you plan to take a short snooze, a neck pillow and a pair of noise-canceling headphones will also be useful. Finally, leave space for a toothbrush and some cleansing wipes to ensure you arrive feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, blades, fuel and fireworks. Sporting equipment like golf clubs, and objects that could harm other people, such as pepper spray and firearms, aren't allowed in the cabin either.

What to wear on a flight:

  • The narrow aisles of an aircraft are no place for a fashion parade. Layer up with comfy clothing and pack a sweater as it can get chilly in the cabin on long-haul flights. Slightly roomy, flat shoes are also recommended.
  • Unfortunately, a risk of long-haul flights is developing deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity. To prevent this from happening, make the most of every opportunity to walk around the cabin and stretch your legs. Compression socks and tights are another great idea to help minimize this risk.

How to get through airport security fast when flying to Castle Danger?
The secret is to be well prepared before you get to the airport security gate. That way, you'll be hopping onto that plane to Castle Danger in the blink of an eye. Follow these helpful tips and get your vacation off to a flying start:

  • Security personnel first need to determine that you have a valid ID and travel documents before you can proceed any further. Have them in your hand, ready for inspection.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items like your coat, belt and headphones will be required to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go through the machine for inspection. Don't worry though, you'll be back online soon enough.
  • Remove all gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-lock bag.
  • It's also possible you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a smart idea.
  • Airlines won't allow any sharp or pointed objects in your carry-on baggage. If you need to bring these kinds of items, check them in.
