Do you have any tips for my flight to Effingham?
Wherever you're jetting in from, flying can be a seamless experience if you've prepared well. Follow these top travel tips that will help get your Effingham escape started on the right foot. What to pack in your hand luggage:

  • The trick to having a great flight experience is to plan ahead. Start with the essentials: passport, travel documents, bank cards and important medications. Next, bring on board items that'll help keep you occupied, like your laptop or a thrilling novel. It's also wise to bring your chargers, a comfy neck pillow and a pair of noise-canceling headphones. And of course, be sure to toss in toiletry items like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects hiding in your carry-on luggage. Other banned items include explosive or flammable goods, such as aerosol cans and bleach, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in cabin temperature by donning layers, and opt for flat, slightly roomy shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Effingham?
Being organized before you get to the airport will make your getaway to Effingham a piece of cake. Read through our top tips for a stress-free journey past security:

  • Your passport and travel documents will need to be inspected by airport security. Keep them within easy reach so you don't hold up the queue.
  • Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Items such as your jacket, belt and earphones need to go through the machine.
  • All your electronics, including your laptop and phone, are also required to be scanned.
  • Remember to remove gels and liquids from your hand luggage. They often need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
  • It's also likely that you'll need to remove your shoes for scanning, so wearing lightweight sneakers is always a clever 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, pack them in your checked baggage.
