Next, you'll need some entertainment to help pass the time. A thrilling book and a phone filled with your favorite movies are some wonderful options. If you hope to catch a few z's, a comfy neck pillow and a pair of noise-canceling headphones will also come in handy. Finally, leave space for a toothbrush and some cleansing wipes to ensure you step off the plane feeling fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes screwdrivers, knives, fuels and bleaching agents. Sporting equipment like golf clubs, and objects that could injure passengers, such as firearms and ammunition, can't come on board with you either. > > > What to wear on a flight: > > > - Comfort should be your priority when picking what to wear during your flight. Consider your footwear carefully too, as swelling of the feet and ankles can be a side effect of flying. Shoes which are flat and slightly roomy are always a good idea. > - Most travelers are aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. There's plenty you can do to reduce your risk. Don a pair of compression tights or socks, drink plenty of water and remember to keep your legs and feet moving. Walk around the cabin when possible or perform some stretches in your seat. ### How to get through airport security fast when flying to Sunset Hills? > - Airport security personnel first need to establish that you have a valid passport and boarding pass before you can proceed any further. Keep them within easy reach. > - The X-ray machine comes next. Remove anything on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening. > - All your electronic devices, including your phone and laptop, will also need to be scanned. > - Any liquids or gels, such as lip balm or cologne, that you want to take on board must be no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one liter), clear zip-lock bag. > - Choosing your footwear wisely can save you a few precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on shoes usually aren't. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put 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 Sunset Hills.
