How to survive the flight to O'Fallon?
If you’re poorly prepared, air travel can be tough. But there’s no need to panic. Follow these useful tips for a worry-free start to your holiday in O’Fallon.What to pack in your hand luggage:

  • The trick to having a stress-free flight experience is to be prepared. So, let’s start with the essentials: passport, boarding pass, bank cards and daily medications. Next, bring items that’ll help pass the time, like some electronic gadgets or a thrilling book. It’s also wise to bring your chargers, a quality neck pillow and a pair of earplugs. And of course, be sure to squeeze in toiletries like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don’t have sharp objects (like a knife or scissors) lurking in one of the zippers of your hand luggage. Other banned items include explosive or flammable substances, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The aisles of your aircraft are not the best place for a fashion parade. Wear comfortable clothes and bring a cardigan as the temperature can drop in the cabin during long-haul flights. Flat, enclosed shoes are also a good choice.
  • A condition called deep vein thrombosis (DVT) can pose a risk on long-haul flights. It’s the result of blood clotting due to inactivity and poor circulation. Walking around the cabin and doing regular leg and foot exercises while seated helps to prevent this happening. Wearing a good pair of compression tights or socks can also help.

How to get through airport security fast when flying to O'Fallon?
A little pre-planning before you get to the airport can make your getaway to O’Fallon quick and painless. Below you’ll find some handy hints for a speedy journey past security:

  • Security personnel first need to determine that you have a valid ID and travel documents before anything else. Have them in your hand, ready for inspection.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the scanner’s alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They’ll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you’ll have to unplug from the digital world. Your tablet, phone and any other electronic devices also need to be sent through the scanner.
  • Any liquids or gels, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers usually aren’t.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won’t be allowed in the cabin.
