Do you have any tips for my flight to Caseyville?
We've got the lowdown on how to make your flight a stress-free experience. Follow our tips and tricks and you'll be zooming through airport security and discovering Caseyville in no time. What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, travel documents, wallet and daily medications. Next, you'll need some in-flight entertainment to while away the time. A juicy book and a laptop crammed with your favourite movies are some wonderful options. If you plan to take a quick snooze, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, make room for a toothbrush and some facial wipes so you'll step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your trusty pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, flares and matches, are also restricted.

What to wear on a flight:

  • Your top priority is to feel as comfortable as you can. Opt for shoes that are easy to slip on and off, dress in loose, breathable clothing and remember to take a jacket in case it gets cold in the cabin.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Reduce the risks by staying hydrated, keeping your feet and legs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Caseyville?
A little pre-planning before you arrive at the airport can make your trip to Caseyville easy and painless. Check out our useful tips for a speedy journey through security:

  • Security personnel first need to make sure that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them close by, ready for inspection.
  • Next up, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Personal belongings like your belt, coat and earphones need to go through the machine.
  • For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronics must also go through the scanner.
  • Any gels or liquids, such as perfume or toothpaste, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and other heavy-style shoes are usually subjected to extra screening.
  • 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 suitcase. They won't be allowed on board and will be confiscated.
