How to survive the flight to Caseyville?
If you’re poorly prepared, traveling can be challenging. But there’s no need to hit the panic button just yet. Follow these tips and tricks and enjoy a comfortable start to your time in Caseyville.What to pack in your hand luggage:

  • The trick to having a stress-free flight experience is to pack in advance. Start with the essentials: passport, official ID, cash and any vital medications. Next, take on board items that’ll help keep you entertained, like some electronic gadgets or a good read. You’ll also want to pack your chargers, a comfy neck pillow and a pair of headphones. Finally, be sure to chuck in toiletries like a toothbrush, facial wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Pointed or sharp objects, like your beloved Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and fuels, are also prohibited.

What to wear on a flight:

  • Comfort should be your highest priority when deciding what to wear during your flight. Consider your footwear carefully too, as swollen feet and ankles can be a side effect of flying. Flat, slightly roomy shoes are your best bet.
  • A condition called deep vein thrombosis (DVT) is a potential risk on long-haul flights. It’s the result of blood clotting due to inactivity and poor circulation. Doing leg and foot exercises while seated helps to prevent this from occurring. Wearing a good-quality pair of compression socks or tights also helps reduce the risk.

How to get through airport security fast when flying to Caseyville?
Being organized before your flight will help make your getaway to Caseyville a piece of cake. We’ve rounded up some useful tips for a swift journey past security:

  • Be sure to have your passport and travel documents handy. They’re the first items you’ll be asked to present to airport security.
  • Time to strip down. Well sort of. Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn.
  • For just a few moments, you’ll have to unplug from the digital world. Your laptop, phone and any other electronic gadgets will also need to be sent through the scanner.
  • Remember 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 single quart-size (one liter), clear zip-close bag.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you must bring these kinds of items, pack them safely in your checked luggage.
