How to survive the flight to Au?
If you're poorly prepared, travelling can be overwhelming. But there's no need to hit the panic button just yet. Follow these helpful hints and enjoy a pain-free start to your getaway in Au.What to pack in your hand luggage:

  • A plane ride can be a great experience if you take the right stuff. Firstly, you'll need basic toiletry items, such as deodorant and a toothbrush, a spare change of clothes and a good book. Secondly, leave space in your bag for your mobile phone, a charger, any daily medications and maybe a cosy neck pillow as well. Lastly, and most importantly, be sure to take your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects lurking in your carry-on luggage. Other banned items include flammable or explosive products, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The narrow aisles of an airplane are no place for a fashion parade. Layer up with comfortable clothing and don't forget to bring a sweater as the temperature can drop inside the cabin during long-haul flights. Closed-toed, flat shoes are also a wise idea.
  • Unfortunately, one risk of long-haul flights is developing DVT (deep vein thrombosis), a blood clotting condition caused by prolonged periods of inactivity. To avoid this, take every opportunity to walk around the cabin and stretch your legs. Compression socks and tights are another great idea to help minimize this risk.

How to get through airport security fast when flying to Au?
It's all about being prepared. We've rounded up some handy tips and tricks for a fuss-free trip through security. Look out Au, here you come:

  • Airport security personnel first need to check that you have a valid passport and travel documents before you're allowed to proceed any further. Have them ready for inspection.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Items such as your coat, belt and headphones need to go through the machine.
  • For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronic devices also need to be sent through the scanner.
  • Don't forget to remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • There's a good chance you'll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a clever idea.
  • Sharp items like knives are not allowed in the cabin. They'll be seized at security, so pack them safely away in your checked luggage.
