Do you have any tips for my flight to St. Charles?
Depending on where you're coming from, your trip to St. Charles could be completely painless or it could go on forever. We've pulled together some handy tips that will help you start your next great escape on a positive note. What to pack in your hand luggage:

  • A plane trip can be easy if you take the right gear. First things first, you'll need basic toiletries, such as lip balm and hand cream, a fresh change of clothes and a good book. Next, make room in your bag for your phone, tablet and chargers, any medications and maybe a quality neck pillow as well. Lastly, be sure to bring your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your treasured pocket knife, and products which are explosive or flammable, such as flares, chemicals agents and matches, are also restricted.

What to wear on a flight:

  • The aisles of an aircraft aren't the place for a fashion parade. Dress in comfortable layers and go for shoes that are flat, enclosed and easy to remove.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To reduce your risk on board, drink lots of water, consider wearing compression socks or tights and keep your feet and legs moving.

How to get through airport security fast when flying to St. Charles?
It's simple --- be prepared. We've rounded up some top tips for a fuss-free trip through airport security. Look out St. Charles, here you come:

  • Security personnel first need to verify that you have a valid passport and matching travel documents before anything else. Have them ready to show.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronics will need to be sent through the scanner.
  • Travelling with your favourite cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're permitted to bring it with you in your carry-on bag.
  • Choosing your footwear wisely can save you a few precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Airlines will not allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, pack them safely in your checked luggage.
