First up, the essentials: passport, travel docs, credit cards and vital medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a juicy novel. It's also a wise idea to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, be sure to toss in toiletry items like a toothbrush, lip balm and a fresh change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Double-check that you don't have sharp objects (like a knife or scissors) lurking in your hand luggage. Other prohibited items include explosive or flammable goods, such as fuel and fireworks, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - The aisles of an airplane are no place for a fashion parade. Layer up with comfortable clothing and choose shoes that are enclosed, flat and easy to pull on and off. > - The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Lower your risks by staying hydrated, keeping your lower limbs moving and wearing compression socks to help improve your circulation. ### How to get through airport security fast when flying to Waterloo? > - Keep your ID and boarding pass someplace easily accessible. They're the first things you'll be asked for by security. > - Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn. > - Electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online in no time. > - Travelling with your favourite hand and nail cream? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you in your carry-on luggage. > - Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when passing through security. Hiking boots and other bulky shoes are often subjected to extra screening. > - Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you must bring these kinds of items, pack them safely in your checked luggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Waterloo.
