Do you have any tips for my flight to Jefferson?
No matter where you're coming from, flying can be a seamless experience if you're well prepared. We've compiled a list of handy travel tips that will get your Jefferson escape started on the right note. What to pack in your hand luggage:

  • It's easy — first, pack your passport, travel docs, wallet and medications. Next, you'll want some entertainment to help pass the time. A juicy book and a tablet crammed with your favourite shows are some terrific options. If you intend to take a quick nap, a neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some facial wipes to ensure you step off the plane feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a pocket knife hiding in your hand luggage. Other restricted items include explosive or flammable goods, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes by dressing in layers, and opt for flat, easy-to-remove footwear like sneakers.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To reduce your risk on board, drink lots of water, consider wearing compression socks and move your lower limbs often.

How to get through airport security fast when flying to Jefferson?
Being prepared before you arrive at the airport will help make your trip to Jefferson a breeze. Here are some handy tips for a stress-free journey past security:

  • First things first. Your travel documents and passport will need to be shown to security personnel. Have them close by so you don't have to dig around for them.
  • Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Electronic devices like laptops and phones will also need to go on a tray for inspection. Don't worry though, you'll be back online before you know it.
  • Any gels or liquids, such as toothpaste or perfume, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • Slip-on shoes are a good footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and other heavy shoes are usually subjected to additional screening.
  • Sharp items like knives are not allowed on board. They'll be confiscated at security, so put them in your checked luggage.
