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

  • It's simple — first, put in your passport, travel documents, credit cards and medications. Next, you'll need some entertainment to while away the hours. A juicy novel and a phone crammed with your favourite shows are some fantastic options. If you plan to take a short nap, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, find room for a toothbrush and some deodorant to ensure you arrive at your destination looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes screwdrivers, blades, aerosol cans and bleaching agents. Sports equipment like bows and arrows, and objects that could injure passengers, such as swords and batons, can't come on board with you either.

What to wear on a flight:

  • Comfort should be your main priority when choosing what to wear on your flight. Loose clothing is a wise choice, as are flat, slightly roomy shoes.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It's the result of blood clotting due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to Dupont?
The simple answer is — be prepared. We've pulled together some helpful hints for a hassle-free trip through security. Look out Dupont, here you come:

  • Airport security personnel first need to know that you have a valid passport and boarding pass before anything else. Keep them close by.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. 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 electronic devices, including your phone and laptop, must also be scanned separately.
  • Any liquids or gels, such as toothpaste or perfume, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • Choosing your footwear wisely can save you several minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Knives and other sharp items are prohibited in the cabin. They'll be seized at security, so put them in your checked suitcase.
