How to survive the flight to Pilot Knob?
Wherever you're coming from, flying can be a seamless experience if you've prepared well. Follow these top travel tips that will help get your Pilot Knob escape started on the right foot.What to pack in your hand luggage:

  • The trick to having an awesome travel experience is to pack ahead. First up, the essentials: passport, travel documents, credit cards and any vital medications. Next, take on board items that'll help keep you occupied, like your laptop or a good read. You'll also want to pack your chargers, a neck pillow and a pair of earplugs. Finally, be sure to pop in toiletry items like a toothbrush, facial wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) won't be allowed on. Sharp objects, like your pocket knife, and products which are explosive or flammable, such as flares, chemicals agents and matches, are also not allowed.

What to wear on a flight:

  • Your goal here is to be as comfortable as possible. Don layers of natural-fiber clothing and don't forget to pack a cardigan in case it gets cold in the cabin. Opt for roomy, flat shoes as your feet may swell during the flight. Leave the high heels and chunky boots in your checked baggage.
  • Most travelers have heard about deep vein thrombosis (DVT), a blood clot condition caused by reduced mobility or inactivity. There are many ways to minimize your risk. Wear compression tights or socks, stay hydrated and remember to keep your legs and feet moving. Do a lap or two of the cabin or try out some simple stretches in your seat.

How to get through airport security fast when flying to Pilot Knob?
Being organized before you arrive at the airport will make your getaway to Pilot Knob a breeze. Below you'll find some useful tips and tricks for a swift journey through security:

  • Keep your passport and boarding pass close by. They'll be the first things you'll be asked to show at airport security.
  • Time to strip down. Well sort of. Your coat, belt, keys and other small items, like your headphones, will be required to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • For just a few minutes, you'll have to unplug from technology. Your tablet, phone and any other electronics also need to go through the scanner.
  • Traveling with your favorite cologne or perfume? As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you can bring it with you in your carry-on baggage.
  • The right choice of footwear can save you several valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Airlines will not allow any sharp or pointed objects in the cabin. If you must bring these kinds of items, pack them safely in your checked luggage.
