Next, you'll want some extra in-flight entertainment to while away the time. A thrilling novel and a laptop filled with your favourite shows are some great options. If you intend to catch up on some sleep, a quality neck pillow and some earplugs will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes so you'll touchdown feeling fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of banned items can differ between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, drills, fireworks and fuel. Sports equipment like bows and arrows, and items that could injure passengers, such as firearms and swords, 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. Don comfortable layers and pick shoes that are flat, enclosed and easy to remove. > - Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression tights or socks. ### How to get through airport security fast when flying to Prospect Heights? > - Security personnel first need to check that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them close by, ready for inspection. > - 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 things like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt. > - Your electronic devices like laptops and phones will also have to go on a tray to be scanned. No need to worry though, you'll be back online in no time. > - Remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag. > - Slip-on shoes are a great footwear choice as you're less likely to be asked to remove them when passing through security. Hiking boots and other heavy shoes are usually subjected to extra screening. > - Airlines will not allow any sharp or pointed objects to come on board with you. If you must bring these kinds of items, check them in. ## Book with confidence # Expedia flights to Prospect Heights Searching for cheap flights to Prospect Heights?
