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 tricks and you'll be hightailing it through the airport and enjoying Knoxville in no time. What to pack in your hand luggage:

  • The secret to having an awesome flight experience is to plan ahead. First up, the essentials: passport, travel docs, bank cards and medications. Next, bring on board items that'll help while away those hours, like some electronic gadgets or a good book. It's also smart to bring your chargers, a neck pillow and a pair of earphones. Finally, be sure to pop in toiletries like a toothbrush, lip balm and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects lurking in your carry-on luggage. Other restricted items include flammable or explosive products, like aerosols and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your main priority when choosing what to wear on board. Loose clothing is a sensible option, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Knoxville?
The trick is to be well organised before you reach airport security. That way, you'll be boarding that plane to Knoxville in the blink of an eye. Follow these tips and get your holiday off to a spectacular start:

  • Keep your boarding pass and passport close by. They're the first items you'll be asked for by airport security.
  • After that, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Personal belongings such as your belt, coat and earphones need to go through the machine.
  • All your electronics, including your laptop and phone, must also be separately scanned.
  • 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 in a container 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 clever footwear choice as you're less likely to have to remove them when passing through security. Safety boots and other heavy-style shoes are often subjected to extra screening.
  • Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you need to bring these kinds of items, pack them safely in your checked baggage.
