Do you have any tips for my flight to King of Prussia?

  • Wherever you’re going, flying can be an enjoyable experience if you come prepared. First of all, pack your travel documents, passport and medications. Next, throw in a little extra in-flight entertainment to help make the time fly by. A juicy novel and a tablet filled with your favorite movies are a couple of good options. If you plan on getting some sleep, a memory-foam neck pillow and earplugs are also worth bringing along.
  • There’s a lengthy list of items you shouldn’t pack in your carry-on baggage too. Explosives, flammables and sharps are strictly prohibited in the cabin — they can include aerosol cans, flares, box cutters and razor blades. Some sporting equipment, like martial arts weapons and baseball bats, are also not allowed in your hand luggage. Check your airline’s website for details about what you can and can’t take on board.

What to wear on a flight:

  • Choose comfort before fashion when flying. Dress in layers and wear natural materials as they allow moisture and air to pass through and keep you cool. Cabin temperatures can get cold on long-haul flights, so pack a pullover and always wear sneakers or flat, closed-toe shoes.
  • Consider wearing compression tights or socks to reduce the risk of deep vein thrombosis (DVT). This condition is a result of blood clotting that can be caused by long periods of sitting, especially on long journeys. Performing foot and leg stretches in your seat or wandering around the cabin will help improve your circulation.

How can I get a cheap last-minute flight to King of Prussia?
The key to tracking down a cheap, spur-of-the-moment flight to King of Prussia is to stay flexible. You can score a fantastic deal if you’re not tied to specific travel dates, flight times and airlines. Also compare the prices of flying out of and into nearby airports if that’s an option for you.
Where can I learn more about changing or canceling my flight to King of Prussia?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
