Do you have any tips for my flight to Fort Knox?
Depending on where you're coming from, your journey to Fort Knox could be completely stress-free or it could drag on forever. We've compiled some handy travel tips that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • Air travel can be a great experience if you take the right gear. Firstly, you'll want a few toiletry items, such as a toothbrush and some deodorant, a fresh set of clothes and a few magazines. Next, make room in your hand luggage for your phone, tablet and chargers, any daily medications and perhaps a blow-up neck pillow too. Last, but definitely not least, remember to bring your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a Swiss Army knife lurking in one of the zippers of your carry-on luggage. Other prohibited items include flammable or explosive substances, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your main concern when choosing what to wear during your flight. Loose, breathable clothing is a smart option, as are flat, slightly roomy shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Fort Knox?
The simple answer is — be prepared. We've compiled some tips and tricks for a speedy trip through security. Watch out Fort Knox, here you come:

  • Your passport and boarding pass will need to be inspected by airport security. Have them easily accessible so you don't hold up the queue.
  • Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Items like your belt, coat and headphones need to go through the machine.
  • For just a few moments, you'll need to unplug from technology. Your phone, tablet and any other electronic devices will need to go through the scanner.
  • Any liquids or gels, such as perfume or toothpaste, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several valuable minutes. Boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Sharp or pointed objects (like knives and scissors) can't be taken on board. They'll be seized at security, so pack them safely away in your checked suitcase.
