Do you have any tips for my flight to Dupont?
If you're poorly prepared, travelling can be daunting. But there's no need to hit the panic button just yet. Follow these useful tips and enjoy a stress-free start to your getaway in Dupont. What to pack in your hand luggage:

  • A plane trip can be easy if you carry the right things. Firstly, you'll want some toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh change of clothes and a magazine or two. Secondly, find a spot in your carry-on bag for your electronic gadgets, chargers, any vital medications and perhaps a quality neck pillow too. Lastly, don't forget to bring your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your precious pocket knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and fuels, are also not allowed.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Layer up with comfy clothing and opt for shoes that are flat, enclosed and easy to take on and off.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To lower your risk on board, drink plenty of water, consider wearing compression socks and do gentle foot and leg exercises in your seat.

How to get through airport security fast when flying to Dupont?

  • Your belt, coat, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn.
  • Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Travelling with a new cologne or perfume? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on.
  • There's a good chance you'll need to remove your shoes for scanning, so wearing lightweight sneakers is always a wise idea.
  • Airlines won't allow any sharp objects in your carry-on luggage. If you need to bring these kinds of items, put them in your checked luggage.
