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 tips and tricks and you'll be zooming through airport security and having a ball in St. Charles before you know it. What to pack in your hand luggage:
  • It's easy — first, pack in your passport, important documents, credit cards and vital medications. Next, you'll want some extra in-flight entertainment to while away the time. A juicy novel and a tablet filled with your favourite shows are some wonderful options. If you intend to catch forty winks, a quality neck pillow and some noise-cancelling headphones will also be useful. Finally, leave space for a toothbrush and some deodorant so you'll arrive at your destination feeling fresh and raring to go.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items differs between airlines, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like box cutters, razor blades, spray paint and flares. Sports equipment like bows and arrows, and items that could harm passengers, such as firearms and swords, won't be allowed on board either.
What to wear on a flight:
  • Comfort should be your main concern when choosing what to wear on board. Loose, breathable clothing is a smart option, as are enclosed shoes like sneakers.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To reduce your risk on board, drink plenty of water, consider wearing compression socks and move your legs and feet often.
How to get through airport security fast when flying to St. Charles?
The trick is to be organised before you arrive at the security gate. That way, you'll be stepping onto that plane to St. Charles in a flash. Follow these helpful tips and get your holiday off to a terrific start:
  • Be sure to have your travel documents and ID someplace easily accessible. They're the first things you'll be asked to present to security.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Personal belongings such as your belt, jacket and headphones will be required to go through the machine.
  • All electronic devices, including your laptop and phone, will also need to be separately scanned.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a clever footwear choice as you're less likely to be required to remove them when going through security. Big boots and other bulky shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked suitcase. They won't be allowed on board.
