How to survive the flight to Knife River?
Depending on where you're coming from, your trip to Knife River could be a breeze or it could drag on forever. We've rounded up some useful travel tips 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 pack the right gear. First of all you'll need basic toiletries, such as a toothbrush and lip balm, a spare change of clothes and a good read. Next, find room in your bag for your electronic devices, chargers, your important medications and perhaps a proper neck pillow as well. Lastly, remember to take your passport, travel docs and your credit cards.
Do not pack the following items in your hand luggage:
  • While the list of restricted items differs between airlines, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, blades, aerosol cans and flares. Sports equipment like ice skates, and items that could harm passengers, such as swords and guns, can't come on board with you either.
What to wear on a flight:
  • The narrow aisles of your airplane are not the place for a fashion parade. Layer yourself up with comfortable clothes and bring a sweater as it can get chilly inside the cabin on long-haul flights. Flat, enclosed shoes are also a wise idea.
  • Unfortunately, a risk of long-distance flying is developing deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity. To avoid this, take every opportunity to stretch your legs and walk around the cabin. Compression tights and socks are another simple way to help minimize this risk.
How to get through airport security fast when flying to Knife River?
A little pre-planning before your flight can make your getaway to Knife River a pleasure. Below you'll find some handy hints for a swift journey past security:
  • Security personnel first need to check that you have a valid passport and matching travel documents before anything else. Have them ready for inspection.
  • Time to strip down. Well sort of. Your coat, belt, keys and other items in your pocket, like coins, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • Your electronic devices like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online before you know it.
  • Remove all liquids and gels from your hand luggage. They usually need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-close bag.
  • It's also likely that you'll need to remove your shoes to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed on board and will be confiscated.
