How to survive the flight to Jefferson?
If you're not prepared, travelling can be tough. But there's no need to worry. Follow these useful tips for a worry-free start to your time in Jefferson.What to pack in your hand luggage:

  • The secret to having a pain-free travel experience is to plan ahead. Start with the essentials: passport, official ID, bank cards and any vital medications. Next, take on board items that'll help while away those hours, like some electronic devices or a magazine. You'll also want to pack your chargers, a comfy neck pillow and a pair of earphones. And of course, be sure to toss in toiletries like a toothbrush, facial wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a pocket knife) lurking in one of the zippers of your carry-on luggage. Other banned items include flammable or explosive goods, like aerosols and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Comfort should always be your priority when selecting what to wear during your flight. Consider your footwear with care too, as swelling of the feet and ankles are quite common. Flat shoes which are slightly roomy are your best bet.
  • Unfortunately, one risk of flying long-haul is developing DVT (deep vein thrombosis), a blood clotting condition caused by lengthy periods of inactivity. To prevent this from happening, make the most of every opportunity to walk around and give your legs a stretch. Compression tights and socks are another simple way to help minimize this risk.

How to get through airport security fast when flying to Jefferson?
As seasoned travellers know, the secret is to be well organised before you get to the security gate. That way, you'll be stepping onto that plane to Jefferson in no time at all. Follow these tips and get your trip off to a fantastic start:

  • First things first. Your travel ID and boarding pass will need to be shown to airport security personnel. Have them close by to avoid fumbling around for them.
  • Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • For just a few moments, you'll need to unplug from the digital world. Your phone, tablet and any other electronic gadgets will also need to go through the scanner.
  • Want to bring along your favourite cologne? As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, it's fine to bring with you on board.
  • It's also likely that you'll be asked to remove your shoes for scanning, so wearing lightweight sneakers is always a good idea.
  • Airlines won't allow any sharp items or pocket knives in the cabin. If you must bring these kinds of items, pack them in your checked baggage.
