Do you have any tips for my flight to Lake St Louis?

We've got the lowdown on how to make your flight a stress-free experience. Follow our tips and you'll be cruising through the airport and enjoying Lake St Louis before you know it. What to pack in your hand luggage:

  • The trick to having a great travel experience is to pack in advance. First up, the essentials: passport, boarding pass, bank cards and daily medications. Next, bring items that'll help keep you occupied, like some electronic devices or a good read. It's also smart to bring your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Last but not least, don't forget to squeeze in toiletries like a toothbrush, deodorant and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your beloved Swiss Army knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and strong acids, are also restricted.

What to wear on a flight:

  • The aisles of an airplane are no place for a fashion parade. Wear layers and opt for shoes that are flat, roomy and easy to pull on and off.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Lake St Louis?

The answer is simple — be prepared. We've rounded up some top tips for an easy trip through airport security. Watch out Lake St Louis, here you come:

  • Keep your travel documents and passport within easy reach. They'll be the first things you'll be asked to present to airport security.
  • Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Items such as your belt, coat and earphones will be required to go through the machine.
  • All your electronic devices, including your laptop and phone, must also be scanned separately.
  • Remove all gels and liquids from your carry-on bag. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Airlines won't allow any pocket knives or other sharp items in the cabin. If you must bring these kinds of items, put them in your checked baggage.
