So, let's start with the basics: passport, boarding pass, bank cards and important medications. Next, bring items that'll help keep you occupied, like some electronic devices or a good book. It's also wise to pack your chargers, a quality neck pillow and a pair of headphones. And of course, don't forget to pop in toiletry items like a toothbrush, deodorant and a clean T-shirt. > > > Do not pack the following items in your hand luggage: > > > - While the list of restricted items can differ between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes things like tools, metal cutlery, fireworks and fuel. Sporting equipment like bows and arrows, and items that could harm passengers, such as guns and swords, are also banned from the cabin. > > > What to wear on a flight: > > > - The aisles of an airplane aren't the place for a fashion parade. Dress in comfortable layers and opt for shoes that are flat, enclosed and easy to pull on and off. > - It's likely you've 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 tights or socks and move your lower limbs often. ### How to get through airport security fast when flying to Wilmington? > - First things first. Your travel documents and ID will need to be presented to airport security. Keep them handy so you don't have to dig around for them. > - Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like your headphones, will need to go through the X-ray machine. Make the whole process faster by removing them as your turn draws near. > - Electronic devices like laptops and phones will also have to go through the machine for inspection. Don't worry, you'll be back online in no time. > - Travelling with your favourite cologne or perfume? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's fine to bring with you in your carry-on bag. > - Slip-on shoes are a sensible footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and other heavy-style shoes are usually subjected to extra screening. > - Sharp or pointed items are not allowed in the cabin. They'll be confiscated 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 Wilmington.
