How to survive the flight to Copalis Crossing?
Wherever you're jetting in from, flying can be an enjoyable experience if you've prepared well enough. We've made a list of handy hints that will help get your Copalis Crossing vacation started on the right foot.What to pack in your hand luggage:
  • Flying can be a great experience if you bring the right gear. First things first, you'll need basic toiletry items, such as a toothbrush and hairbrush, a spare set of clothes and something to read. Secondly, leave space in your carry-on bag for your electronic gadgets, chargers, any vital medications and maybe a blow-up neck pillow too. Lastly, and most importantly, be sure to bring your passport, travel docs and your credit cards.

Do not pack the following items in your hand luggage:
  • Make sure you don't have a pocket knife hiding in one of the zippers of your hand luggage. Other banned items include explosive or flammable products, such as aerosol cans and bleach, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:
  • The narrow aisles of an airplane are not the best place for a fashion parade. Don comfortable layers and remember to take a cardigan as the temperature can drop inside the cabin. Flat, enclosed shoes are also a sensible choice.
  • Most travelers have heard about DVT (deep vein thrombosis), a blood clot condition caused by reduced mobility or inactivity. There are numerous ways to reduce your risk. Wear a pair of compression tights or socks, drink lots of water often and get your legs and feet moving. Do a lap or two of the cabin or perform some stretches in your seat.

How to get through airport security fast when flying to Copalis Crossing?
The answer is --- be prepared. We've put together some useful tips for a hassle-free trip through security. Watch out Copalis Crossing, here you come:
  • Your passport and boarding pass will need to be shown to security personnel. Keep them handy so you don't hold up the line.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • All your electronic devices, including your phone and tablet, are also required to be scanned separately.
  • Want to bring along your favorite perfume or cologne? As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be asked to remove them when passing through security. Hiking boots and other heavy-style shoes are often subjected to additional screening.
  • Sharp items are prohibited in the cabin. They'll be confiscated at security, so pack them in your checked suitcase.
