Do you have any tips for my flight to Sidney?
Wherever you're jetting in from, flying can be a pleasant experience if you've prepared well enough. Take a peek at these handy hints that will get your Sidney vacation started on the right foot. What to pack in your hand luggage:

  • The secret to having an awesome travel experience is to plan ahead. First up, the essentials: passport, official ID, cash and daily medications. Next, bring items that'll help keep you occupied, like your laptop or a magazine. It's also smart to pack your chargers, a comfy neck pillow and a pair of earphones. Last but not least, be sure to squeeze in toiletries like a toothbrush, facial wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your beloved pocket knife, and products which are explosive or flammable, such as spray paint, flares and poisons, are also not allowed.

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on board. Loose, breathable clothing is a smart choice, as are flat, slip-on shoes.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Lower your risks by staying hydrated, keeping your lower limbs moving and wearing compression socks or tights.

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

  • Your travel documents and ID will need to be presented to airport security. Keep them handy so you don't hold up the queue.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronic gadgets must also go through the scanner.
  • Any gels or liquids, such as perfume or hairspray, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
  • Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when passing through security. Boots and heavier-style shoes are usually subjected to extra screening.
  • Airlines will not allow any sharp or pointed objects in your carry-on baggage. If you must bring these kinds of items, put them in your checked baggage.
