Next, you'll want some extra in-flight entertainment to while away the hours. A juicy book and a laptop crammed with your favourite shows are some great options. If you intend to take a short nap, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, find room for a toothbrush and some cleansing wipes so you'll hop off the plane looking fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your trusty pocket knife, and products which are flammable or explosive, such as aerosols and fuels, are also prohibited. > > > What to wear on a flight: > > > - Comfort should be your main concern when deciding what to wear on board. Loose, breathable clothing is a smart choice, as are flat, slightly roomy shoes. > - Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Williamstown? > - Airport security personnel first need to make sure that you have a valid passport and matching boarding pass before anything else. Have them in your hand, ready for inspection. > - After that, both you and your hand luggage will be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items like your belt, coat and headphones will be required to go through the machine. > - All electronic devices, including your tablet and phone, are also required to be separately scanned. > - Remove gels and liquids from your hand luggage. They usually 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 in a single quart-size (one litre), clear zip-close bag. > - Slip-on shoes are a practical footwear choice as you're less likely to have to remove them when going through security. Safety boots and other heavy shoes are often subjected to extra 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 safely away in your checked suitcase. They won't be allowed on board and will be confiscated. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Williamstown.
