Do you have any tips for my flight to Caledonia?
If you're poorly prepared, air travel can be overwhelming. But there's no need to hit the panic button just yet. Follow these useful tips for a pleasant start to your getaway in Caledonia. What to pack in your hand luggage:

  • The trick to having a worry-free flight experience is to pack ahead. So, let's start with the basics: passport, boarding pass, bank cards and any vital medications. Next, bring items that'll help keep you occupied, like some electronic devices or a thrilling novel. 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 chuck in toiletry items like a toothbrush, cleansing wipes and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your trusty Swiss Army knife, and dangerous goods which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also not allowed.

What to wear on a flight:

  • Your aim here is to feel as comfortable as you can. Choose shoes that are easy to slip on and off, dress in loose, natural-fibre clothing and remember to bring a sweater in case it gets cold in the cabin.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long-haul flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks or tights.

How to get through airport security fast when flying to Caledonia?
The answer is simple — be organised. We've put together some handy tips and tricks for a stress-free trip through security. Look out Caledonia, here you come:

  • First things first. Your passport and boarding pass will need to be presented to airport security personnel. Keep them handy so you don't hold up the line.
  • Time to strip down. Well kind of. Your jacket, belt, keys and other contents of your pockets, like your headphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic devices will need to go through the scanner.
  • Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to have to remove them when going through security. Big boots and heavier-style shoes are usually subjected to extra screening.
  • Sharp items such as knives and scissors are not allowed on board. They'll be seized at security, so pack them safely away in your checked baggage.
