How to survive the flight to Potosi?
Wherever you're jetting in from, flying can be a seamless experience if you've prepared well enough. Take a peek at these handy tips that will get your Potosi vacation started on the right note.What to pack in your hand luggage:

  • It's simple — first, pack your passport, official ID, bank cards and medications. Next, you'll want some in-flight entertainment to while away the hours. A juicy book and a laptop filled with your favorite movies are always good options. If you intend to take a short snooze, a quality neck pillow and a pair of noise-canceling headphones will also come in handy. Finally, leave space for a toothbrush and some cleansing wipes so you'll arrive at your destination looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a Swiss Army knife lurking in your carry-on luggage. Other prohibited items include flammable or explosive substances, 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 answer to a comfortable flight is often as simple as your choice in clothes. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin gets chilly. Shoes like sandals and heels are best left for other occasions. Instead, go for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • Unfortunately, a risk of long flights is developing DVT (deep vein thrombosis), a blood clot condition caused by prolonged inactivity. To prevent this, take every opportunity to wander around the cabin. Compression socks and tights are another great idea to help reduce this risk.

How to get through airport security fast when flying to Potosi?
The secret is to be prepared before you reach security. That way, you'll be stepping onto that plane to Potosi in no time at all. Follow these tips and get your trip off to a flying start:

  • Be sure to keep your boarding pass and passport close by. They'll be the first things you'll be asked for by security.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to beep. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronic gadgets, including your tablet and phone, will also need to be separately scanned.
  • Any gels or liquids, such as shampoo or hairspray, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-close bag.
  • There's a chance you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a wise idea.
  • Airlines won't allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, pack them in your checked baggage.
