First up, the essentials: passport, travel documents, credit cards and important medications. Next, take on board items that'll help keep you busy, like your laptop or a good book. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of headphones. Finally, don't forget to chuck in toiletry items like a toothbrush, facial wipes and a clean set of clothes. > > > Do not pack the following items in your hand luggage: > > > - Squeeze all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, flares and fireworks, are also prohibited. > > > What to wear on a flight: > > > - You'll want to choose comfort over style. Prepare for temperature changes in the cabin by donning layers, and pick flat, closed-toe footwear like sneakers. > - You've probably heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To minimize your risk on board, drink plenty of water, consider wearing compression socks and keep your legs and feet moving. ### How to get through airport security fast when flying to Deer Park? > - Keep your passport and travel documents handy. They're the first things you'll be asked for by airport security. > - The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening. > - For just a few minutes, you'll have to unplug from the digital world. Your tablet, phone and any other electronic gadgets will need to be sent through the scanner. > - Want to bring along your favourite hand and nail cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's fine to bring with you in your carry-on baggage. > - 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. Lightweight sneakers usually aren't. > - Airlines will not allow any sharp objects in the cabin. If you must bring these kinds of items, put them in your checked luggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Deer Park.
