Do you have any tips for my flight to Princeton?
Wherever you're jetting in from, flying can be a pleasurable experience if you're well organised. Follow these top travel tips that will help get your Princeton holiday started on the right note. What to pack in your hand luggage:

  • First of all, put in your passport, important documents, cash and medications. Next, you'll need some extra in-flight entertainment to while away the time. A thrilling novel and a laptop filled with your favourite movies are good options. If you intend to take a quick snooze, a comfy neck pillow and some earplugs will also come in handy. Finally, find room for a toothbrush and some deodorant to ensure you step off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes things like knives, scissors, fuel and fireworks. Sports equipment like baseball bats, and items that could harm passengers, such as swords and guns, aren't allowed in the cabin either.

What to wear on a flight:

  • The aisles of an aircraft aren't the place for a fashion parade. Dress in comfortable layers and opt for shoes that are flat and easy to take on and off.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Princeton?
As seasoned travellers know, the secret is to be organised before you arrive at security. That way, you'll be hopping onto that plane to Princeton in a flash. Follow these tips and get your holiday off to a spectacular start:

  • Security personnel first need to determine that you have a valid passport and travel documents before you can proceed any further. Have them ready to show.
  • 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 heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronics will need to go through the scanner.
  • Can't travel without your favourite hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can bring it with you in your carry-on bag.
  • There's a good chance you'll be asked to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Airlines will not allow any sharp items or pocket knives in the cabin. If you need to bring these kinds of items, put them in your checked luggage.
