Next, you'll need some in-flight entertainment to help pass the time. A juicy novel and a laptop crammed with your favourite movies are some fantastic options. If you intend to catch more than just forty winks, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some cleansing wipes to ensure you arrive at your destination feeling fresh and raring to go. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have a Swiss Army knife hiding in the bottom of your carry-on luggage. Other prohibited items include flammable or explosive substances, such as fuel and fireworks, and gels and liquids in containers larger than 3.4 ounces (100 milliliters). > > > What to wear on a flight: > > > - Comfort should be your main priority when picking what to wear on board. Consider your choice of footwear carefully too, as swelling of the feet and ankles are a common side effect of flying. Slightly roomy, flat shoes are your best bet. > - The result of lengthy periods of inactivity, DVT (deep vein thrombosis) is a serious condition that can affect passengers on long-haul flights. The great news is there are ways to reduce your risk of developing it. Keep your fluids up, get up and wander the aisles as often as possible and wear compression tights or socks. ### How to get through airport security fast when flying to Princeton? > - Be sure to have your ID and boarding pass easily accessible. They're the first things you'll be asked for by security. > - Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Items such as your belt, coat and earphones will be required to go through the machine. > - All electronic devices, including your laptop and phone, must also be separately scanned. > - Any gels or liquids, such as shampoo or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), zip-lock bag. > - Choosing your footwear wisely can save you a few precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on shoes are usually not. > - Sharp items like knives are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked bags. ## Book with confidence # Expedia flights to Princeton Searching for cheap flights to Princeton?
