Start with the essentials: passport, official ID, bank cards and daily medications. Next, take on board items that'll help while away those hours, like some electronic devices or a good book. You'll also want to pack your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. And of course, be sure to pop in toiletries like a toothbrush, cleansing wipes and a clean T-shirt. > > > Do not pack the following items in your hand luggage: > > > - While the list of restricted items can differ between air carriers, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes things like knives, scissors, spray paint and fireworks. Sports equipment like hockey sticks, and items that could harm passengers, such as guns and swords, can't come on board with you either. > > > What to wear on a flight: > > > - You'll want to choose comfort over style. Prepare for changes in temperature by layering up, and wear flat, slightly roomy footwear like slip-ons. > - Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Lower your risks by drinking water, keeping your legs and feet moving and wearing compression socks to help your circulation. ### How to get through airport security fast when flying to Sidney? > - Be sure to keep your boarding pass and passport easily accessible. They're the first items you'll be asked to show at security. > - Time to strip down. Well sort of. Your coat, belt, keys and other small items, like coins, will be required to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives. > - Electronic devices like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online soon enough. > - Remove all liquids and gels from your hand luggage. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag. > - Choosing your footwear wisely can save you a few precious minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers are usually not. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed on board and will be confiscated. ## Book with confidence # Expedia flights to Sidney Searching for cheap flights to Sidney?
