Do you have any tips for my flight to Charleston?
Depending on where you're coming from, your journey to Charleston could be a breeze or it could go on forever. Here are some useful hints that will help you start your next big adventure on a positive note. What to pack in your hand luggage:

  • A plane ride can be a stress-free experience if you carry the right things. First things first, you'll need toiletry items, such as a toothbrush and lip balm, a spare change of clothes and a good book. Secondly, find a spot in your hand luggage for your laptop, a charger, any medications and maybe a cosy neck pillow as well. Last, but definitely not least, don't forget to bring your passport, travel papers and some cash.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a sharp object hiding in the bottom of your carry-on luggage. Other restricted items include flammable or explosive substances, such as aerosol cans and fuel, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of a plane are no place for a fashion parade. Wear layers and go for shoes that are flat, roomy and easy to take on and off.
  • You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lower your risk on board, drink lots of water, consider wearing compression tights or socks and move your legs and feet often.

How to get through airport security fast when flying to Charleston?
A little pre-planning before you get to the airport will help make your trip to Charleston a breeze. Check out our handy tips for a swift journey through security:

  • Be sure to keep your boarding pass and passport close by. They're the first things you'll be asked for by security.
  • Time to strip down. Well sort of. Your coat, belt, keys and other small items, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few moments, you'll need to unplug from the digital world. Your phone, tablet and any other electronic devices will also need to be sent through the scanner.
  • Remove all liquids and gels from your hand luggage. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to have to remove them when going through security. Safety boots and other bulky shoes are often subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed on board.
