How to survive the flight to Caldelas?
Wherever you're jetting in from, flying can be a pleasurable experience if you've prepared well enough. We've compiled a list of essential travel tips that will get your Caldelas vacation started on the right foot.What to pack in your hand luggage:

  • The trick to having an amazing flight experience is to pack ahead. First up, the essentials: passport, travel documents, bank cards and any vital medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a thrilling novel. You'll also want to bring your chargers, a quality neck pillow and a pair of headphones. Finally, don't forget to squeeze in toiletry items like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a pocket knife) lurking in the bottom of your hand luggage. Other banned items include flammable or explosive substances, such as bleach and fuel, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The key to a comfortable flight can be as simple as the clothes you wear. Prepare for temperature changes by bringing layers. That way you'll stay nice and warm if the cabin begins to cool down. Shoes like flip flops and heels are best left in your checked suitcase. Even though they may be your favorites, opt for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a condition that can affect passengers during long-haul flights. But the good news is there are proven ways to significantly reduce the risk of developing it. Stay hydrated, wander around the cabin wherever possible and wear compression socks or tights.

How to get through airport security fast when flying to Caldelas?
A little pre-planning before you get to the airport will make your trip to Caldelas a piece of cake. We've rounded up some handy tips for a stress-free journey through security:

  • Security personnel first need to make sure that you have a valid ID and matching travel documents before you're allowed to proceed any further. Keep them close by.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • All electronic devices, including your tablet and phone, must also be scanned separately.
  • Traveling with a new cologne or perfume? As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on luggage.
  • Choosing your footwear wisely can save you several minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you must bring these kinds of items, pack them in your checked luggage.
