Do you have any tips for my flight to St. Charles?
Depending on where you're coming from, your flight to St. Charles could be no sweat at all or it could go on forever. Here are some useful tips that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:
  • A plane ride can be a stress-free experience if you bring the right things. Firstly, you'll want some basic toiletries, such as a toothbrush and lip balm, a fresh set of clothes and a few magazines. Next, make room in your carry-on bag for your phone and charger, any medications and maybe a proper neck pillow as well. Last, but definitely not least, be sure to bring your passport, travel papers and your credit cards.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have sharp objects (like a pocket knife) hiding in your hand luggage. Other restricted items include flammable or explosive goods, such as aerosol cans and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Go for comfort over style. Prepare for changes in cabin temperature by wearing layers, and pick flat, enclosed footwear like slip-ons.
  • You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression socks and keep your feet and legs moving.
How to get through airport security fast when flying to St. Charles?
It's easy — be prepared. We've pulled together some tips and tricks for a speedy trip through airport security. Watch out St. Charles, here you come:
  • Your boarding pass and travel ID will need to be inspected by airport security personnel. Have them easily accessible to avoid fumbling around for them.
  • The X-ray machine comes next. Remove anything metal on you that is likely to beep. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronics, including your tablet and phone, must also be scanned.
  • Any liquids or gels, such as lip balm or cologne, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • There's a possibility that you'll be required to take your shoes off to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won't be allowed on board and will be confiscated.
