How to survive the flight to High Valley?
Depending on where you're coming from, your trip to High Valley could be simple and straightforward or it could go on forever. We've pulled together some handy tips that will help you start your next great adventure on the right foot.What to pack in your hand luggage:

  • The secret to having a great flight experience is to pack ahead. First up, the essentials: passport, travel docs, credit cards and any vital medications. Next, bring on board items that'll help pass the time, like some electronic gadgets or a thrilling novel. It's also wise to pack your chargers, a comfy neck pillow and a pair of headphones. Last but not least, be sure to chuck in toiletries like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule to follow is nothing flammable, sharp or explosive. This includes things like screwdrivers, pocket knives, spray paint and flares. Sporting equipment like bows and arrows, and objects that could harm passengers, such as pepper spray and guns, won't be allowed on board either.

What to wear on a flight:

  • Comfort should always be the goal when choosing what to wear during your flight. Consider your choice of footwear with care too, as swelling of the feet and ankles are a common side effect of flying. Slightly roomy, flat shoes are always a smart option.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a condition that can affect some passengers on long-haul flights. The great news is there are ways to reduce your risk of developing it. Drink plenty of water, get up and wander the aisles as much as you can and wear compression socks or tights.

How to get through airport security fast when flying to High Valley?
As seasoned travellers know, the secret is to be prepared before you reach the security gate. That way, you'll be boarding that plane to High Valley in the blink of an eye. Follow these tips and get your trip off to a flying start:

  • First things first. Your travel documents and passport will need to be shown to airport security. Keep them at hand so you don't have to dig around for them.
  • Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them before your turn.
  • For just a few minutes, you'll have to unplug from technology. Your laptop, phone and any other electronic devices will also need to go through the scanner.
  • Remove all gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a good footwear choice as you're less likely to be asked to remove them when going through security. Boots and other heavy shoes are usually subjected to additional screening.
  • Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you must bring these kinds of items, pack them in your checked luggage.
