Do you have any tips for my flight to St. Charles?
We've got the lowdown on how to make your journey as stress-free as possible. Follow our top tips and you'll be speeding through airport security and exploring St. Charles in no time. What to pack in your hand luggage:
  • A plane ride can be a comfortable experience if you take the right stuff. Firstly, you'll want a few basic toiletries, such as a toothbrush and some deodorant, a fresh change of clothes and a magazine or two. Secondly, find a spot in your carry-on bag for your electronic gadgets, chargers, any vital medications and maybe a neck pillow as well. Lastly, don't forget to bring your passport, travel documents and some cash.
Do not pack the following items in your hand luggage:
  • While the list of banned items can differ between air carriers, the general rule of thumb is nothing sharp, flammable or explosive. This includes knives, scissors, spray paint and fireworks. Sports equipment like baseball bats, and items that could harm passengers, such as swords and guns, can't come on board with you either.
What to wear on a flight:
  • Your main priority is to feel as comfortable as you can. Choose shoes that are easy to slip on and off, dress in loose, breathable clothing and remember to bring a pullover in case it gets cold in the cabin.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To lessen your risk on board, stay hydrated, consider wearing compression socks and move your legs and feet often.
How to get through airport security fast when flying to St. Charles?
It's all about being prepared. We've put together some top tips for an easy trip through security. Look out St. Charles, here you come:
  • Be sure to have your travel documents and passport someplace easily accessible. They'll be the first things you'll be asked to present to airport security.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your laptop and phone, will also need to be scanned separately.
  • Any liquids or gels, such as hair oil or hand cream, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and other heavy shoes are usually subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed in the cabin.
