Do you have any tips for my flight to Caseyville?
No matter where you're coming from, flying can be a pleasurable experience if you've planned ahead. We've made a list of handy tips and tricks that will help get your Caseyville vacation started on the right foot. What to pack in your hand luggage:

  • First things first, pack in your passport, travel docs, bank cards and daily medications. Next, you'll want some in-flight entertainment to help pass the time. A juicy novel and a tablet crammed with your favourite shows are some wonderful options. If you intend to catch up on some sleep, a quality neck pillow and some noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some deodorant so you'll arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like screwdrivers, drills, fireworks and fuel. Sports equipment like ice skates, and objects that could injure passengers, such as guns and swords, won't be allowed on board either.

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes in the cabin by donning layers, and pick closed-toe, flat shoes like slip-ons.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Caseyville?
Being organized before you get to the airport will help make your getaway to Caseyville quick and painless. Below are some top tips for a swift journey through security:

  • Be sure to keep your passport and boarding pass someplace easily accessible. They're the first things you'll be asked to present to security.
  • Your belt, coat, keys and other small items, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • All electronic devices, including your laptop and phone, must also be scanned.
  • Travelling with a new perfume or cologne? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you in your carry-on luggage.
  • Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when going through security. Big boots and other bulky shoes are often subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won't be allowed on board.
