How to survive the flight to Fort Knox?
If you’re poorly prepared, traveling can be challenging. But there’s no need to worry. Follow these handy tips for a pain-free start to your vacation in Fort Knox.What to pack in your hand luggage:

  • It’s easy — first, put in your passport, official ID, credit cards and vital medications. Next, you’ll want some in-flight entertainment to help pass the time. A thrilling book and a tablet filled with your favorite shows are some great options. If you hope to catch more than just forty winks, a comfy neck pillow and a pair of noise-canceling headphones will also be useful. Finally, leave space for a toothbrush and some facial wipes so you’ll hop off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes tools, metal cutlery, fireworks and fuel. Sports equipment like bows and arrows, and items that could injure passengers, such as swords and batons, won’t be allowed on board either.

What to wear on a flight:

  • The best way to ensure a comfortable flight is as simple as your choice of clothing. Prepare for changes in temperature by bringing layers. That way you’ll stay nice and warm if the cabin gets chilly. 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 sneakers. Your feet will thank you later.
  • Most travelers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. There are numerous ways to lower your risk. Wear compression socks or tights, drink lots of water often and remember to keep your legs and feet moving. Wander around the cabin or try out some simple stretches in your seat.

How to get through airport security fast when flying to Fort Knox?
It’s easy — be prepared. We’ve pulled together some top tips for a speedy trip through security. Watch out Fort Knox, here you come:

  • Your passport and travel documents will need to be inspected by airport security. Keep them within easy reach to avoid fumbling around for them.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the scanner’s alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They’ll need to be placed on the conveyor belt for screening.
  • All your electronic devices, including your phone and laptop, must also be separately scanned.
  • Remove all gels and liquids from your carry-on bag. They often need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag.
  • Choosing your footwear wisely can save you valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you need to bring these kinds of items, pack them in your checked baggage.
