Do you have any tips for my flight to Williston?
If you're not prepared, air travel can be challenging. But there's no need to panic. Follow these useful tips for a hassle-free start to your time in Williston. What to pack in your hand luggage:
  • The trick to having a pain-free travel experience is to plan ahead. First up, the essentials: passport, travel documents, credit cards and vital medications. Next, bring on board items that'll help pass the time, like your laptop or a magazine. It's also smart to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. Last but not least, don't forget to toss in toiletry items like a toothbrush, facial wipes and a clean set of clothes.
Do not pack the following items in your hand luggage:
  • Put all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like a Swiss Army knife, and dangerous products which are explosive or flammable, such as spray paint, flares and gasoline, are also prohibited.
What to wear on a flight:
  • The aisles of an airplane aren't the place for a fashion parade. Dress in comfortable layers and go for shoes that are flat, roomy and easy to remove.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation.
How to get through airport security fast when flying to Williston?
The simple answer is — be prepared. We've pulled together some handy tips and tricks for a fuss-free trip through airport security. Watch out Williston, here you come:
  • Your travel documents and ID will need to be presented to airport security personnel. Keep them handy so you don't hold up the queue.
  • Next up, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items such as your belt, jacket and earphones need to go through the machine.
  • Your electronic devices like laptops and phones will also have to go on a tray for inspection. Don't worry though, you'll be back online in no time.
  • Don't forget to remove gels and liquids from your hand luggage. They often 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-close bag.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be required to remove them when going through security. Safety boots and other heavy shoes are often subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won't be allowed on board and will be confiscated.
