How to survive the flight to Dupont?
Wherever you're coming from, flying can be an enjoyable experience if you've planned ahead. We've made a list of handy hints that will get your Dupont escape started on the right note.What to pack in your hand luggage:

  • First, pack in your passport, official ID, wallet and vital medications. Next, you'll need some in-flight entertainment to while away the time. A juicy novel and a laptop filled with your favourite movies are some great options. If you hope to take a short nap, a quality neck pillow and a pair of earplugs will also come in handy. Finally, squeeze in a toothbrush and some facial wipes so you'll step off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp or pointed objects, like your beloved Swiss Army knife, and dangerous goods which are flammable or explosive, such as flares, bleaching agents and matches, are also prohibited.

What to wear on a flight:

  • The long, narrow aisles of your airplane are no place for a fashion parade. Layer up with comfy clothing and take a sweater as it tends to get cool inside the cabin on long-haul flights. Closed-toed, flat shoes are also a good choice.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by reduced mobility or inactivity. There are numerous ways to lessen your risk. Wear a pair of compression socks or tights, drink lots of water and move your legs and feet. Wander around the cabin or perform exercises in your seat.

How to get through airport security fast when flying to Dupont?
The secret is to be organised before you reach airport security. That way, you'll be stepping onto that plane to Dupont in no time at all. Follow these tips and get your trip off to a great start:

  • Airport security personnel first need to establish that you have a valid ID and travel documents before you're allowed to proceed any further. Have them within easy reach, ready for inspection.
  • Time to strip down. Well kind of. Your coat, belt, keys and other contents of your pockets, like your headphones, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronics will need to be sent through the scanner.
  • Want to bring along your favourite cologne? Not a problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you're permitted to bring it with you in your carry-on baggage.
  • There's a good chance you'll be asked to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Sharp items are not allowed in the cabin. They'll be confiscated at security, so put them in your checked baggage.
