Do you have any tips for my flight to King of Prussia?
Wherever you're jetting in from, flying can be a pleasurable experience if you prepare well enough. Follow these handy tips that will help get your King of Prussia escape started on the right note. What to pack in your hand luggage:

  • The secret to having an amazing travel experience is to pack ahead. So, let's start with the essentials: passport, travel docs, bank cards and medications. Next, bring items that'll help keep you occupied, like your laptop or a magazine. You'll also want to pack your chargers, a neck pillow and a pair of earplugs. And of course, don't forget to pop in toiletry items like a toothbrush, facial wipes and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hair gel in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your treasured pocket knife, and products which are explosive or flammable, such as aerosol cans, flares and fireworks, are also not allowed.

What to wear on a flight:

  • Comfort should be your highest priority when deciding what to wear on your flight. Loose clothing is a wise option, as are flat, slip-on shoes.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To lessen your risk on board, drink lots of water, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to King of Prussia?
Being prepared before your flight will help make your trip to King of Prussia quick and painless. Here are some useful tips and tricks for a swift journey past security:

  • Have your ID and travel documents within close reach. They're the first items you'll be asked for by airport security.
  • Time to strip down. Well sort of. Your coat, belt, keys and other items in your pocket, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn.
  • For just a few minutes, you'll have to unplug from the digital world. Your tablet, phone and any other electronic devices also need to be sent through the scanner.
  • Any gels or liquids, such as perfume or hairspray, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • It's also likely that you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a smart idea.
  • Airlines will not allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, put them in your checked baggage.
