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

  • It's simple — first, pack in your passport, official ID, wallet and vital medications. Next, you'll want some entertainment to help pass the time. A juicy novel and a tablet crammed with your favourite movies are always good options. If you plan to catch forty winks, a comfy neck pillow and some earplugs will also come in handy. Finally, squeeze in a toothbrush and some deodorant to ensure you arrive looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a knife or scissors) hiding in your carry-on luggage. Other banned items include explosive or flammable products, such as fuel and fireworks, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your main concern when choosing what to wear on your flight. Loose clothing is a sensible choice, as are flat, slip-on shoes.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Reduce the risks by staying hydrated, keeping your legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Williamstown?
Being prepared before you arrive at the airport can make your trip to Williamstown a breeze. We've rounded up some useful tips for a stress-free journey through security:

  • First things first. Your boarding pass and passport will need to be presented to security personnel. Have them easily accessible so you don't hold up the queue.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • Electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry though, you'll be back online in no time.
  • Any gels or liquids, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • There's a good chance you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a good idea.
  • Sharp items like knives are not allowed in the cabin. They'll be seized at security, so put them in your checked bags.
