Do you have any tips for my flight to St. Charles?
We've rounded up all the info you need to make your flight a pleasant experience. Follow our insider tips and you'll be cruising through airport security and having a ball in St. Charles in no time flat. What to pack in your hand luggage:

  • Air travel can be easy if you pack the right gear. First of all you'll need basic toiletries, such as toothpaste, a toothbrush and some deodorant, a fresh change of clothes and a few magazines. Next, find a spot in your carry-on bag for your phone and charger, your medications and perhaps a cozy neck pillow too. Last, but definitely not least, remember to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like a Swiss Army knife, and dangerous products which are explosive or flammable, such as flares, chemicals agents and strong acids, are also not allowed.

What to wear on a flight:

  • Comfort should be your main concern when deciding what to wear during your flight. Loose, breathable clothing is a smart choice, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to St. Charles?
As seasoned travellers know, the secret is to be organized before you reach the security gate. That way, you'll be stepping onto that plane to St. Charles in a flash. Follow these tips and get your trip off to a fantastic start:

  • First things first. Your travel documents and passport will need to be presented to airport security personnel. Have them close by so you don't hold up the queue.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll need to unplug from the digital world. Your phone, laptop and any other electronic devices will also need to be sent through the scanner.
  • Don't forget to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several minutes. Boots are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Sharp items such as knives and scissors are prohibited in the cabin. They'll be seized at security, so put them in your checked bags.
