How to survive the flight to Knoxville?
If you’re poorly prepared, airports and flying can be daunting. But there’s no need to panic. Follow these handy hints and enjoy a trouble-free start to your getaway in Knoxville.What to pack in your hand luggage:

  • First things first, put in your passport, travel docs, wallet and vital medications. Next, you’ll need some entertainment to while away the time. A juicy novel and a phone crammed with your favorite shows are some fantastic options. If you hope to catch up on some sleep, a quality neck pillow and some earplugs will also be useful. Finally, make room for a toothbrush and some cleansing wipes so you’ll arrive looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Pointed or sharp objects, like your trusty pocket knife, and dangerous goods which are flammable or explosive, such as flares, bleaching agents and strong acids, are also restricted.

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on board. Consider your choice of footwear with care too, as swollen feet can be a side effect of flying. Roomy, closed-toed shoes are always a smart option.
  • Most travelers are aware of DVT (deep vein thrombosis), a blood clot condition caused by long periods of sitting. There are plenty of ways to reduce your risk. Don a pair of compression socks or tights, stay hydrated and move your legs and feet. Walk around the cabin when possible or try out some exercises in your seat.

How to get through airport security fast when flying to Knoxville?
The answer is — be prepared. We’ve pulled together some useful tips for a speedy trip through airport security. Watch out Knoxville, here you come:

  • Your passport and boarding pass will need to be shown to airport security. Have them close by to avoid fumbling around for them.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes items like headphones or earphones, as well as your coat or jacket. They’ll need to be placed on the conveyor belt for screening.
  • Electronic devices like laptops and phones will also have to go on a tray to be scanned. Don’t worry though, you’ll be back online in no time.
  • Want to bring along your favorite perfume or cologne? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it’s stored in a zip-lock bag, you can bring it with you in your carry-on.
  • The right choice of footwear can save you several valuable minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Knives and other sharp items are not allowed on board. They’ll be confiscated at security, so put them in your checked bags.
