First up, the essentials: passport, travel documents, credit cards and vital medications. Next, bring on board items that'll help keep you occupied, like your laptop or a few magazines. It's also wise to pack your chargers, a quality neck pillow and a pair of headphones. Last but not least, be sure to pop in toiletries like a toothbrush, lip balm and a fresh change of clothes. > > > Do not pack the following items in your hand luggage: > > > - While the list of restricted items can differ between airlines, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes box cutters, razor blades, fireworks and fuel. Sporting equipment like bows and arrows, and items that could harm passengers, such as swords and batons, can't come on board with you either. > > > What to wear on a flight: > > > - The aisles of an aircraft aren't the place for a fashion parade. Wear layers and opt for shoes that are closed-toe, flat and easy to take on and off. > - Deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks. ### How to get through airport security fast when flying to Casco? > - Security personnel first need to establish that you have a valid passport and matching boarding pass before anything else. Have them within easy reach, ready for inspection. > - The X-ray machine comes next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt. > - All your electronic gadgets, including your laptop and phone, must also be scanned separately. > - Travelling with a new perfume? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you in your carry-on. > - There's a chance you'll be asked to take your shoes off for scanning, so wearing lightweight sneakers is always a smart idea. > - 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 Casco.
