How to survive the flight to O'Fallon?
No matter where you’re coming from, flying can be an enjoyable experience if you’ve planned ahead. Check out these top travel tips that will help get your O’Fallon escape started on the right foot.What to pack in your hand luggage:

  • Travelling on a plane can be a cruisy experience if you pack the right things. First of all you’ll need toiletry items, such as a toothbrush and hairbrush, a spare change of clothes and a magazine or two. Secondly, leave space in your bag for your phone and charger, any vital medications and maybe a quality neck pillow too. Lastly, don’t forget to bring your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes knives, scissors, fuels and bleaching agents. Sporting equipment like hockey sticks, and objects that could harm passengers, such as firearms and ammunition, aren’t allowed in the cabin either.

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on board. Consider your choice of footwear carefully too, as swollen ankles and feet are a common side effect of flying. Roomy, closed-toed shoes are your best bet.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-haul flights. The good news is there are proven ways to lower your risk of developing it. Drink plenty of water, get up and walk around the cabin as much as you can and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to O'Fallon?
Being prepared before you get to the airport will make your getaway to O’Fallon a piece of cake. Check out our useful tips and tricks for a stress-free journey past security:

  • Airport security personnel first need to check that you have a valid ID and matching travel documents before you can proceed any further. Have them ready for inspection.
  • After that, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might set the alarms off. Personal belongings such as your coat, belt and headphones need to go through the machine.
  • All your electronics, including your phone and laptop, will also need to be scanned separately.
  • Remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a clever footwear choice as you’re less likely to have to remove them when going through security. Boots and heavier-style shoes are often subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked baggage. They won’t be allowed on board and will be confiscated.
