> - Air travel can be a cruisy experience if you've got all the right stuff. Firstly, you'll need basic toiletries, such as lip balm and hand cream, a spare change of clothes and a magazine or two. Secondly, find room in your hand luggage for your electronic devices, chargers, medications and maybe a comfy neck pillow too. Lastly, be sure to take your passport, travel papers and your credit cards.
> 
>   
> Do not pack the following items in your hand luggage:
> 
>   
> - Leave all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Pointed or sharp objects, like your precious pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and poisons, are also banned.
> 
>   
> What to wear on a flight:
> 
>   
> - Comfort really should be your prime concern when choosing what to wear on your flight. Consider your choice of footwear with care too, as swollen feet and ankles can be a side effect of flying. Shoes which are flat and slightly roomy are always a sensible way to go.
> - Most travelers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by reduced mobility or inactivity. There are plenty of ways to lower your risk. Wear a good-quality pair of compression socks or tights, drink lots of water and move your legs and feet. Walk around the cabin when possible or try out some simple stretches in your seat.

### How to get through airport security fast when flying to Saint Charles?

> - Be sure to have your ID and boarding pass easily accessible. They're the first items you'll be asked for by airport security.
> - Time to strip down. Well kind of. Your jacket, belt, keys and other small items, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them before your turn arrives.
> - All your electronic devices, including your phone and tablet, are also required to be scanned.
> - Remember to remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-lock bag.
> - There's a chance you'll need to remove your shoes for scanning, so wearing slip-on sneakers is always a wise idea.
> - Airlines won't allow any pocket knives or other sharp items to come on board with you. If you need to bring these kinds of items, pack them in your checked baggage.
