How to survive the flight to Keystone?
Depending on where you’re coming from, your journey to Keystone could be as easy as pie or it could go on forever. We’ve rounded up some useful tips that will help you start your next big adventure on the right foot.What to pack in your hand luggage:

  • Flying can be a stress-free experience if you bring the right gear. Firstly, you’ll need toiletry items, such as deodorant, toothpaste and a toothbrush, a clean set of clothes and a good read. Secondly, make room in your carry-on bag for your phone, tablet and chargers, your medications and perhaps a proper neck pillow too. Last, but definitely not least, remember to take your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Double-check that you don’t have a Swiss Army knife lurking in the bottom of your carry-on luggage. Other restricted items include explosive or flammable substances, such as aerosol cans and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The aisles of your airplane are not the best place for a fashion parade. Layer up with comfy clothing and remember to take a cardigan as it can get quite cool in the cabin. Enclosed, flat shoes are also a good idea.
  • Unfortunately, a risk of long-haul flights is developing deep vein thrombosis (DVT), a blood clot condition caused by prolonged inactivity. To prevent this from happening, take every opportunity to walk around the cabin and stretch your legs. Compression tights and socks are another easy way to help lower your risk.

How to get through airport security fast when flying to Keystone?
A little pre-planning before you get to the airport will make your trip to Keystone a pleasure. Below are some handy tips and tricks for a swift journey through security:

  • Your boarding pass and travel ID will need to be presented to security personnel. Keep them within easy reach so you don’t have to dig around for them.
  • After that, both you and your hand luggage must be X-rayed. To speed things up, take off anything that might trigger the alarms. Items such as your belt, coat and headphones will be required to go through the machine.
  • Electronic devices like phones and laptops will also have to go through the machine to be scanned. Don’t worry though, you’ll be back online before you know it.
  • Can’t travel without your favourite hand and nail cream? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it’s stored in a clear zip-close bag, you’re allowed to bring it with you on board.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Pocket knives and other sharp items can’t be taken on board. They’ll be confiscated at security, so pack them safely away in your checked suitcase.
