How to survive the flight to Princeton?
Depending on where you’re coming from, your journey to Princeton could be no sweat at all or it could drag on forever. Here are some handy tips that will help you start your unforgettable escape on a positive note.What to pack in your hand luggage:

  • The trick to having a great flight experience is to pack ahead. So, let’s start with the essentials: passport, boarding pass, bank cards and daily medications. Next, bring items that’ll help keep you busy, like some electronic gadgets or a juicy novel. It’s also smart to pack your chargers, a comfy neck pillow and a pair of earphones. Last but not least, be sure to chuck in toiletry items like a toothbrush, lip balm and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Sharp objects, like your precious Swiss Army knife, and dangerous goods which are flammable or explosive, such as aerosol cans, spray paint and fireworks, are also prohibited.

What to wear on a flight:

  • The goal here is to make yourself as comfortable as you can. Layer up with loose, natural-fiber clothing and remember to bring a sweater in case it gets cool. Opt for flat, well-fitting shoes as it’s possible that your feet and ankles will swell a little during the flight. Leave the stilettos and heavy boots in your checked luggage.
  • The serious condition known as DVT (deep vein thrombosis) is a potential risk on long-haul flights. It results from blood clotting due to inactivity and poor circulation. Walking around the cabin and doing regular foot and leg exercises in your seat is a great way to prevent this from happening. Wearing a high-quality pair of compression tights or socks can also help.

How to get through airport security fast when flying to Princeton?
A little pre-planning before you get to the airport will help make your getaway to Princeton easy and painless. Below you’ll find some handy tips for a speedy journey past security:

  • Security personnel first need to verify that you have a valid ID and boarding pass before you’re allowed to proceed any further. Have them in your hand, 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 jackets or coats. They’ll all need to go on the X-ray conveyor belt.
  • Your electronic devices like laptops and phones will also have to go through the machine for inspection. Don’t worry though, you’ll be back online before you know it.
  • Remember to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-close bag.
  • There’s a chance you’ll be asked to take your shoes off for scanning, so wearing slip-on sneakers is always a wise idea.
  • Sharp or pointed objects (like knives and scissors) are not allowed on board. They’ll be seized at security, so pack them in your checked luggage.
