Do you have any tips for my flight to Knoxville?
We've pulled together all the info you need to make your flight a pleasant experience. Follow our tips and you'll be zooming through the airport and exploring Knoxville in no time. What to pack in your hand luggage:
  • The trick to having a pain-free travel experience is to pack ahead. So, let's start with the essentials: passport, boarding pass, bank cards and daily medications. Next, take on board items that'll help keep you busy, like some electronic gadgets or a few magazines. You'll also want to pack your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Last but not least, don't forget to pop in toiletries like a toothbrush, deodorant and a clean T-shirt.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items can differ between air carriers, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes box cutters, razor blades, fuels and bleaching agents. Sporting equipment like bows and arrows, and objects that could injure passengers, such as swords and batons, can't come on board with you either.
What to wear on a flight:
  • You'll want to go for comfort over style. Prepare for temperature changes in the cabin by dressing in layers, and pick slightly roomy, flat shoes like sneakers.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lessen your risk on board, stay hydrated, consider wearing compression socks or tights and move your lower limbs often.
How to get through airport security fast when flying to Knoxville?
It's easy — be prepared. We've put together some handy tips and tricks for a stress-free trip through security. Watch out Knoxville, here you come:
  • Be sure to keep your boarding pass and passport close by. They're the first items you'll be asked to show at airport security.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic devices also need to be sent through the scanner.
  • Any gels or liquids, such as perfume or hairspray, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other heavy shoes are often subjected to additional screening.
  • Airlines won't allow any sharp or pointed objects in your hand luggage. If you need to bring these kinds of items, pack them in your checked luggage.
