How to survive the flight to Weldon Spring Heights?
If you're not prepared, travelling can be daunting. But there's no need to worry. Follow these tips and tricks for a stress-free start to your time in Weldon Spring Heights.What to pack in your hand luggage:

  • Flying can be a cruisy experience if you carry the right things. First things first, you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a spare change of clothes and a magazine or two. Secondly, find room in your bag for your mobile phone, a charger, any daily medications and maybe a neck pillow too. Lastly, don't forget to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and fireworks, are also restricted.

What to wear on a flight:

  • The main aim is to make yourself as comfortable as you can. Layer up with loose, breathable clothing and take a pullover in case it gets cold in the cabin. Opt for a pair of flat, slightly roomy shoes as it's possible that your feet and ankles will swell during the journey. Leave the stilettos and chunky boots in your luggage.
  • The serious condition by the name of DVT (deep vein thrombosis) is a risk on long-haul flights. It's the result of blood clots forming due to inactivity and poor circulation. Doing foot and leg exercises in your seat helps to prevent this occurring. Wearing a high-quality pair of compression socks or tights is also recommended.

How to get through airport security fast when flying to Weldon Spring Heights?
It's all about being prepared. We've compiled some helpful hints for an easy trip through security. Watch out Weldon Spring Heights, here you come:

  • First things first. Your travel ID and boarding pass will need to be presented to security personnel. Have them close by so you don't have to dig around for them.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll need to unplug from technology. Your laptop, phone and any other electronic gadgets will need to be sent through the scanner.
  • Any liquids or gels, such as hair oil or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Sharp items like knives can't be taken on board. They'll be seized at security, so put them in your checked bags.
