So, let's start with the essentials: passport, official ID, bank cards and medications. Next, bring on board items that'll help keep you occupied, like some electronic devices or a few magazines. You'll also want to pack your chargers, a comfy neck pillow and a pair of earphones. And of course, be sure to chuck in toiletries like a toothbrush, cleansing wipes and a spare change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Pack all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your trusty Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, flares and strong acids, are also not allowed. > > > What to wear on a flight: > > > - The aisles of an aircraft are no place for a fashion parade. Layer up with comfortable clothing and pick shoes that are roomy, flat and easy to remove. > - 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 simple exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Aviston? > - Your passport and boarding pass will need to be presented to airport security. Keep them within easy reach to avoid fumbling around for them. > - 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 your coat or jacket. They'll need to be placed on the conveyor belt for screening. > - All electronic devices, including your tablet and phone, are also required to be scanned separately. > - Remember to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray separately. Each product 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-lock bag. > - There's a chance you'll be required to remove your shoes for scanning, so wearing slip-on shoes is always a clever idea. > - Sharp or pointed items are prohibited in the cabin. They'll be seized at security, so pack them in your checked baggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Aviston.
