How to survive the flight to Hillside?
If you're poorly prepared, airports and flying can be testing. But there's no need to panic. Follow these helpful hints for a stress-free start to your holiday in Hillside.What to pack in your hand luggage:
  • The secret to having a stress-free flight experience is to pack ahead. So, let's start with the basics: passport, boarding pass, bank cards and medications. Next, bring items that'll help while away those hours, like some electronic devices or a juicy novel. It's also smart to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. And of course, don't forget to pop in toiletry items like a toothbrush, cleansing wipes and a clean set of clothes.
Do not pack the following items in your hand luggage:
  • Squeeze all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Sharp objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as flares, chemicals agents and matches, are also not allowed.
What to wear on a flight:
  • The key to a comfortable flight can be as simple as your choice of clothing. Prepare for temperature changes by layering up. This will keep you nice and warm if the cabin gets too cold. Shoes like stilettos, flip flops and lace-up boots are best left in your suitcase. Even though they may be your favourites, opt for flat, closed-toed footwear like sneakers. Your feet will appreciate it.
  • Caused by lengthy periods of inactivity, DVT (deep vein thrombosis) is a serious condition that can affect some passengers on long-haul flights. But the great news is there are numerous ways to reduce your risk of developing it. Stay well hydrated, wander through the cabin as often as you can and wear compression socks or tights.
How to get through airport security fast when flying to Hillside?
The answer is simple — be prepared. We've rounded up some handy tips and tricks for a hassle-free trip through security. Watch out Hillside, here you come:
  • Keep your travel documents and passport handy. They're the first items you'll be asked to present to security.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • For just a few moments, you'll need to unplug from the digital world. Your phone, tablet and any other electronic devices will need to be sent through the scanner.
  • Any liquids or gels, such as shampoo or hand cream, that you want to bring on board must be no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • There's a possibility that you'll be required to take your shoes off for scanning, so wearing slip-on shoes is always a smart idea.
  • Knives and other sharp items are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked suitcase.
