Do you have any tips for my flight to Dem?
Wherever you're jetting in from, flying can be a pleasurable experience if you're well prepared. We've made a list of handy hints that will get your Dem holiday started on the right foot. What to pack in your hand luggage:

  • Flying can be a stress-free experience if you bring the right gear. Firstly, you'll want some basic toiletries, such as a toothbrush and lip balm, a fresh set of clothes and a good book. Secondly, make room in your bag for your electronic gadgets, chargers, your important medications and perhaps a cosy neck pillow as well. Last, but definitely not least, don't forget to bring your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other restricted items include flammable or explosive goods, such as fuel and fireworks, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an airplane are no place for a fashion parade. Wear layers and choose shoes that are flat, enclosed and easy to take on and off.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To minimize your risk on board, drink plenty of water, consider wearing compression socks and keep your legs and feet moving.

How to get through airport security fast when flying to Dem?
As seasoned travellers know, the secret is to be prepared before you get to the security gate. That way, you'll be boarding that plane to Dem in no time flat. Follow these helpful tips and get your holiday off to a great start:

  • First things first. Your boarding pass and travel ID will need to be shown to airport security. Keep them someplace accessible to avoid fumbling around for them.
  • Time to strip down. Well kind of. Your jacket, belt, keys and other items in your pocket, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • All your electronic gadgets, including your phone and laptop, will also need to be separately scanned.
  • Travelling with a new hand cream? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you on board.
  • There's a chance you'll be asked to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a good idea.
  • Sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked baggage.
