Do you have any tips for my flight to Niwot?
We've got the lowdown on how to make your journey an enjoyable experience. Follow our tips and you'll be zooming through airport security and having a blast in Niwot in no time at all. What to pack in your hand luggage:

  • It's simple — first, put in your passport, travel docs, bank cards and daily medications. Next, you'll want some entertainment to while away the time. A juicy book and a phone crammed with your favourite shows are some fantastic options. If you hope to take a quick snooze, a comfy neck pillow and some earplugs will also come in handy. Finally, make room for a toothbrush and some facial wipes so you'll hop off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes things like knives, scissors, aerosol cans and bleaching agents. Sporting equipment like baseball bats, and items that could injure passengers, such as swords and guns, can't come on board with you either.

What to wear on a flight:

  • Your aim is to feel as comfortable as you can. Choose slip-on footwear, dress in loose, breathable clothing and remember to bring a pullover in case you get cold in the cabin.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To lower your risk on board, drink lots of water, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to Niwot?
The simple answer is — be prepared. We've rounded up some top tips for an easy trip through security. Watch out Niwot, here you come:

  • Your ID and travel documents will need to be shown to security personnel. Keep them handy so you don't hold up the queue.
  • After that, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings like your belt, jacket and headphones will be required to go through the machine.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronics will also need to go through the scanner.
  • Remember to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed in the cabin.
