Do you have any tips for my flight to Knox?
If you're not prepared, airports and flying can be daunting. But there's no need to hit the panic button just yet. Follow these tips and tricks for a trouble-free start to your time in Knox. What to pack in your hand luggage:

  • First, pack in your passport, travel documents, cash and medications. Next, you'll need some extra in-flight entertainment to help pass the time. A thrilling novel and a laptop crammed with your favourite shows are some fantastic options. If you hope to catch forty winks, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, leave some space for a few toiletry items to ensure you arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your treasured Swiss Army knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and strong acids, are also prohibited.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for changes in temperature by layering up, and opt for easy-to-remove footwear like sneakers.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long flights. Lower your risks by drinking water, keeping your ankles and legs moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Knox?
As savvy travellers know, the secret is to be well prepared before you arrive at the airport security gate. That way, you'll be hopping onto that plane to Knox in the blink of an eye. Follow these tips and get your trip off to a spectacular start:

  • Have your passport and travel documents easily accessible. They're the first items you'll be asked to show at security.
  • After that, both you and your hand luggage will be X-rayed. To speed things up, take off anything that is likely to trigger the alarm. Items like your belt, coat and headphones need to go through the machine.
  • For just a few minutes, you'll have to unplug from the digital world. Your phone, tablet and any other electronic devices must also go through the scanner.
  • Any liquids or gels, such as perfume or toothpaste, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • It's also likely that you'll be required to take your shoes off for scanning, so wearing slip-on shoes is always a good idea.
  • Airlines won't allow any pocket knives or other sharp items in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked luggage.
