Next, you'll want some extra in-flight entertainment to while away the time. A thrilling novel and a tablet filled with your favourite movies are good options. If you intend to catch more than just forty winks, a comfy neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, squeeze in a toothbrush and some deodorant so you'll arrive at your destination looking and feeling fresh. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have sharp or pointed objects lurking in one of the zippers of your hand luggage. Other prohibited items include explosive or flammable goods, such as fuel and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Your aim is to feel as comfortable as possible. Opt for a pair of flat, closed-toe shoes, dress in loose, natural-fibre clothing and remember to bring a jacket in case you get chilly in the cabin. > - You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and keep your legs and feet moving. ### How to get through airport security fast when flying to Williamson? > - Airport security personnel first need to establish that you have a valid passport and boarding pass 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 speed things up, remove anything that is likely to trigger the alarm. Personal belongings like your jacket, belt and headphones need to go through the machine. > - For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic gadgets will need to go through the scanner. > - Want to bring along your favourite perfume? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's OK to bring with you in your carry-on. > - Slip-on shoes are a good footwear choice as you're less likely to have to remove them when passing through security. Big boots and other heavy-style shoes are often subjected to additional screening. > - Take all prohibited items out of 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. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Williamson.
