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

  • Flying can be a pleasure if you take the right things. Firstly, you'll want some basic toiletry items, such as a toothbrush and some deodorant, a clean set of clothes and a good read. Secondly, leave space in your hand luggage for your phone, tablet and chargers, any medications and maybe a blow-up neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp or pointed objects, like a pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, spray paint and fireworks, are also prohibited.

What to wear on a flight:

  • The long, narrow aisles of your plane are not the best place for a fashion parade. Layer up with comfy clothing and bring a sweater as it can get chilly in the cabin. Flat, slightly roomy shoes are also a wise idea.
  • Most travelers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. There are many ways to reduce your risk. Wear a pair of compression socks or tights, stay hydrated and get your legs and feet moving. Wander up and down the aisles of the cabin or perform some simple exercises in your seat.

How to get through airport security fast when flying to Casteau?
The answer is — be prepared. We've put together some tips and tricks for a hassle-free trip through airport security. Look out Casteau, here you come:

  • First things first. Your travel documents and ID will need to be presented to security personnel. Keep them within easy reach so you don't hold up the queue.
  • Your coat, belt, keys and other small items, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
  • For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic devices also need to go through the scanner.
  • Don't forget to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag.
  • It's also possible you'll be required to take your shoes off for scanning, so wearing lightweight sneakers is always a smart idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked luggage. They won't be allowed on board.
