How to survive the flight to Piasa?
If you're not prepared, traveling can be challenging. But there's no need to worry. Follow these useful tips for a worry-free start to your time in Piasa.What to pack in your hand luggage:
  • The trick to having a stress-free flight experience is to pack in advance. Start with the essentials: passport, travel docs, cash and daily medications. Next, bring items that'll help keep you busy, like your laptop or a good book. It's also smart to bring your chargers, a neck pillow and a pair of headphones. Finally, don't forget to pop in toiletry items like a toothbrush, facial wipes and a fresh change of clothes.
Do not pack the following items in your hand luggage:
  • Make sure you don't have a Swiss Army knife hiding in your hand luggage. Other prohibited items include flammable or explosive goods, such as fuel and fireworks, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).
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. That way you'll stay nice and warm if the cabin begins to cool down. Shoes like stilettos, flip flops and lace-up boots are best left in your checked suitcase. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will thank you later.
  • The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. But the great news is there are numerous ways to reduce the risk of developing it. Stay well hydrated, wander around the cabin as much as possible and wear compression tights or socks.
How to get through airport security fast when flying to Piasa?
The answer is simple — be prepared. We've compiled some handy tips and tricks for an easy trip through airport security. Look out Piasa, here you come:
  • Have your passport and boarding pass within easy reach. They're the first items you'll be asked for by airport security.
  • Your jacket, belt, keys and other items in your pocket, like coins, will need to go on a tray through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • All your electronics, including your phone and tablet, are also required to be separately scanned.
  • Any gels or liquids, such as shampoo or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one liter), clear zip-lock bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Sharp or pointed items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked baggage.
