First things first, you'll need basic toiletries, such as a toothbrush and hairbrush, a clean set of clothes and a few magazines. Secondly, find room in your hand luggage for your phone and charger, any daily medications and maybe a cosy neck pillow too. Lastly, don't forget to bring your passport, travel docs and your credit cards. > > > Do not pack the following items in your hand luggage: > > > - Leave all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your beloved pocket knife, and products which are flammable or explosive, such as aerosols and fuels, are also banned. > > > What to wear on a flight: > > > - The aisles of a plane aren't the place for a fashion parade. Layer up with comfortable clothing and opt for shoes that are flat, enclosed and easy to take on and off. > - The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. Reduce the risks by drinking water, 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 verify that you have a valid ID and boarding pass before anything else. Have them ready for inspection. > - Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt. > - For just a few minutes, you'll have to unplug from technology. Your tablet, phone and any other electronic devices also need to be sent through the scanner. > - Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag. > - There's a possibility that you'll need to remove your shoes for scanning, so wearing slip-on shoes is always a clever idea. > - Airlines won't allow any pocket knives or other sharp items in your carry-on baggage. If you need to bring these kinds of items, put them in your checked baggage. ## Book with confidence # Expedia flights to Princeton Searching for cheap flights to Princeton?
