First, pack in your passport, important documents, credit cards and vital medications. Next, you'll want some entertainment to help pass the time. A juicy novel and a laptop crammed with your favourite movies are good options. If you intend to take a quick nap, a quality neck pillow and a pair of earplugs will also come in handy. Finally, squeeze in a toothbrush and some deodorant so you'll arrive at your destination looking fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - Make sure you don't have sharp objects (like a pocket knife) lurking in the bottom of your carry-on luggage. Other restricted items include explosive or flammable products, such as bleach and fuel, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Comfort should be your priority when deciding what to wear on board. Loose, breathable clothing is a wise choice, as are flat, slip-on shoes. > - The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Lower your risks by staying hydrated, keeping your legs moving and wearing compression socks to help improve your circulation. ### How to get through airport security fast when flying to Princeton? > - Airport security personnel first need to see that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection. > - Your belt, coat, keys and other items in your pocket, like your earphones, will be required to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives. > - Your electronic gadgets like phones and laptops will also have to go through the machine to be scanned. No need to worry though, you'll be back online in no time. > - Any gels or liquids, such as perfume or hairspray, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag. > - Lightweight sneakers are a practical footwear choice as you're less likely to have to remove them when going through security. Safety boots and other heavy shoes are usually subjected to extra screening. > - Airlines won't allow any pocket knives or other sharp items to come on board with you. If you need to bring these kinds of items, put them in your checked luggage. ## Book with confidence # Expedia flights to Princeton Searching for cheap flights to Princeton?
