Start with the essentials: passport, travel docs, credit cards and medications. Next, bring on board items that'll help while away those hours, like your laptop or a juicy novel. It's also smart to bring your chargers, a neck pillow and a pair of earphones. Finally, be sure to toss in toiletries like a toothbrush, deodorant and a spare set of clothes. > > > Do not pack the following items in your hand luggage: > > > - Leave all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like a pocket knife, and dangerous products which are flammable or explosive, such as aerosol cans, spray paint and fuels, are also restricted. > > > What to wear on a flight: > > > - The aisles of an aircraft are no place for a fashion parade. Don comfortable layers and pick shoes that are closed-toe, flat and easy to take on and off. > - Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some gentle exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Thornton? > - Keep your travel documents and ID within easy reach. They're the first things you'll be asked to present to airport security. > - The X-ray machine is up next. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening. > - For just a few minutes, you'll have to unplug from technology. Your phone, tablet and any other electronic gadgets will also need to be sent through the scanner. > - Remember to remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag. > - Choosing your footwear wisely can save you a few precious minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't. > - Airlines won't allow any sharp items or pocket knives in the cabin.
