Start with the essentials: passport, official ID, bank cards and medications. Next, bring items that'll help while away those hours, like some electronic devices or a thrilling book. It's also wise to bring your chargers, a neck pillow and a pair of headphones. Finally, don't forget to toss in toiletry items like a toothbrush, facial wipes and a fresh set of clothes. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items differs between air carriers, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, knives, spray paint and fireworks. Sporting equipment like ski poles, and objects that could harm other people, such as swords and guns, can't come on board with you either. > > > What to wear on a flight: > > > - The aisles of an airplane are no place for a fashion parade. Layer up with comfortable clothing and go for shoes that are closed-toe, flat and easy to take on and off. > - Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Preston? > - Security personnel first need to know that you have a valid passport and matching boarding pass before you're allowed to proceed any further. Have them within easy reach, ready for inspection. > - Next up is the X-ray machine. Remove anything on you that is likely to set off the 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 your electronic devices, including your tablet and phone, are also required to be separately scanned. > - Remove all liquids and gels from your carry-on luggage. They often 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 inside a quart-size (one litre), clear zip-lock bag. > - It's also likely that you'll be required to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a smart idea. > - Sharp items can't be taken on board. They'll be confiscated at security, so pack them in your checked suitcase. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Preston.
