Do you have any tips for my flight to Challis?
Wherever you're jetting in from, flying can be a pleasurable experience if you prepare well enough. Check out these handy travel tips that will help get your Challis escape started on the right note. What to pack in your hand luggage:

  • It's simple — first, pack in your passport, travel documents, bank cards and daily medications. Next, you'll need some in-flight entertainment to help pass the time. A juicy book and a laptop filled with your favourite shows are always good options. If you intend to take a short snooze, a comfy neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some facial wipes so you'll arrive at your destination looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp objects (like a knife or scissors) lurking in one of the compartments of your hand luggage. Other restricted items include flammable or explosive products, such as bleach and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of an airplane are no place for a fashion parade. Layer up with comfy clothing and choose shoes that are flat and easy to slip on and off.
  • You've probably heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lessen your risk on board, drink plenty of water, consider wearing compression socks and keep your feet and legs moving.

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

  • Airport security personnel first need to check that you have a valid ID and matching travel documents before anything else. Have them close by, ready for inspection.
  • Time to strip down. Well kind of. Your jacket, belt, keys and other items in your pocket, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • For just a few moments, you'll need to unplug from technology. Your phone, laptop and any other electronic gadgets also need to be sent through the scanner.
  • Remove all liquids and gels from your carry-on bag. 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-lock bag.
  • Slip-on shoes are a great footwear choice as you're less likely to be required to remove them when passing through security. Boots and other bulky shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed on board and will be confiscated.
