How to survive the flight to Lake St Louis?
Wherever you’re coming from, flying can be a pleasant experience if you prepare well enough. We’ve made a list of handy tips that will help get your Lake St Louis vacation started on the right note.What to pack in your hand luggage:

  • Air travel can be a comfortable experience if you carry the right things. First things first, you’ll need basic toiletries, such as deodorant and a toothbrush, a fresh set of clothes and something to read. Secondly, make room in your hand luggage for your electronic gadgets, chargers, any vital medications and maybe a proper neck pillow too. Lastly, and most importantly, don’t forget to take your passport, travel docs and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between airlines, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes things like knives, scissors, spray paint and fireworks. Sports equipment like ski poles, and items that could injure passengers, such as firearms and ammunition, are also banned from the cabin.

What to wear on a flight:

  • The best way to ensure a comfortable flight is as simple as your clothing choices. Prepare for changes in temperature by bringing layers. That way you’ll stay nice and warm if the cabin begins to cool down. Shoes like stilettos, flip flops and lace-up boots are best left in your suitcase. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a serious condition that can affect some passengers during long-haul flights. But the great news is there are proven ways to significantly reduce the risk of developing it. Stay hydrated, wander through the cabin as often as you can and wear compression socks or tights.

How to get through airport security fast when flying to Lake St Louis?
Being prepared before your flight can make your trip to Lake St Louis a piece of cake. Check out our top tips for a speedy journey past security:

  • First things first. Your passport and boarding pass will need to be presented to airport security personnel. Keep them someplace accessible so you don’t hold up the line.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to set off the alarm. This includes items like earphones or headphones, as well as your coat or jacket. They’ll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. No need to worry though, you’ll be back online in no time.
  • Don’t forget to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-lock bag.
  • There’s a chance you’ll need to take your shoes off for scanning, so wearing slip-on sneakers is always a good idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won’t be allowed on board.
