Do you have any tips for my flight to Duncan?
Wherever you're coming from, flying can be an enjoyable experience if you're well prepared. We've put together a list of handy tips and tricks that will get your Duncan vacation started on the right note. What to pack in your hand luggage:

  • A plane ride can be a pleasure if you take the right stuff. Firstly, you'll want some toiletry items, such as deodorant and a toothbrush, a clean pair of socks and a good book. Next, leave space in your bag for your phone and charger, medications and maybe a quality neck pillow too. Last, but definitely not least, remember to bring your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a sharp object hiding in your carry-on luggage. Other banned items include explosive or flammable goods, such as fuel and matches, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

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

How to get through airport security fast when flying to Duncan?
It's easy --- be prepared. We've put together some handy tips and tricks for a fuss-free trip through airport security. Look out Duncan, here you come:

  • Security personnel first need to establish that you have a valid passport and boarding pass before you're allowed to proceed any further. Keep them within easy reach.
  • Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings such as your belt, jacket and earphones will be required to go through the machine.
  • All your electronics, including your phone and laptop, are also required to be scanned separately.
  • Can't travel without your favourite perfume? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you in your carry-on.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to have to remove them when passing through security. Boots and other heavy-style shoes are usually subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won't be allowed in the cabin.
