Do you have any tips for my flight to Walnut?
We've rounded up all the info you need to make your journey an enjoyable experience. Follow our insider tips and you'll be hightailing it through the airport and exploring Walnut before you know it. What to pack in your hand luggage:

  • Firstly, and most importantly, pack your passport, travel docs, cash and medications. Next, you'll want some extra in-flight entertainment to help pass the time. A juicy book and a phone filled with your favorite shows are some wonderful options. If you intend to take a short nap, a quality neck pillow and some noise-canceling headphones will also be useful. Finally, leave space for a toothbrush and some deodorant so you'll touchdown looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a pocket knife hiding in the bottom of your hand luggage. Other prohibited items include explosive or flammable substances, such as fuel and matches, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for changes in cabin temperature by layering up, and pick flat, closed-toe shoes like sneakers.
  • Most of us 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 tights or socks and keep your legs and feet moving.

How to get through airport security fast when flying to Walnut?
Being prepared before you arrive at the airport will help make your getaway to Walnut easy and painless. Below you'll find some handy tips for a swift journey past security:

  • Airport security personnel first need to determine that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them ready for inspection.
  • Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Items like your belt, coat and earphones need to go through the machine.
  • Your electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry though, you'll be back online soon enough.
  • Don't forget to remove liquids and gels from your hand luggage. They often 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 in a quart-size (one liter), clear zip-lock bag.
  • Choosing your footwear wisely can save you valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed in the cabin.
