How to survive the flight to Dupo?
We’ve got the lowdown on how to make your journey as stress-free as possible. Follow our tips and you’ll be hightailing it through airport security and discovering Dupo in no time flat.What to pack in your hand luggage:

  • The secret to having a pain-free flight experience is to pack ahead. So, let’s start with the essentials: passport, official ID, bank cards and important medications. Next, bring items that’ll help keep you occupied, like some electronic devices or a magazine. It’s also smart to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. And of course, don’t forget to toss in toiletries like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Pointed or sharp objects, like your trusty pocket knife, and dangerous products which are flammable or explosive, such as flares, bleaching agents and matches, are also not allowed.

What to wear on a flight:

  • The best way to ensure a comfortable flight can be as simple as your clothing choices. Prepare for changes in temperature by layering up. That way you’ll stay nice and warm if the cabin begins to cool down. Shoes like high heels and sandals are best left in your suitcase. Instead, go for flat, closed-toed footwear like sneakers. Your feet will appreciate it.
  • The serious condition known as DVT (deep vein thrombosis) can pose a risk on long-distance flights. It results from blood clotting due to poor circulation. Doing foot and leg exercises while seated helps to prevent this happening. Wearing a pair of compression tights or socks is also a wise idea.

How to get through airport security fast when flying to Dupo?
The trick is to be prepared before you arrive at airport security. That way, you’ll be stepping onto that plane to Dupo in the blink of an eye. Follow these helpful tips and get your holiday off to a terrific start:

  • Airport security personnel first need to know that you have a valid ID and matching boarding pass before anything else. Have them close by, ready for inspection.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They’ll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like phones and laptops will also have to go through the machine to be scanned. Don’t worry though, you’ll be back online before you know it.
  • Any liquids or gels, such as lip balm or cologne, that you want to take on board must be no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • Slip-on shoes are a good footwear choice as you’re less likely to be asked to remove them when passing through security. Hiking boots and other heavy-style shoes are often subjected to extra screening.
  • Airlines will not allow any sharp objects to come on board with you. If you need to bring these kinds of items, pack them in your checked luggage.
