How to survive the flight to Boulder?
Depending on where you’re coming from, your journey to Boulder could be a breeze or it could go on forever. Here are some handy travel tips that will help you start your unforgettable escape on the right foot.What to pack in your hand luggage:

  • The secret to having a stress-free flight experience is to plan ahead. Start with the essentials: passport, travel docs, cash and important medications. Next, bring items that’ll help keep you busy, like some electronic devices or a juicy novel. You’ll also want to pack your chargers, a neck pillow and a pair of earplugs. Finally, be sure to pop in toiletries like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don’t have sharp objects (like a knife or scissors) lurking in your carry-on luggage. Other prohibited items include explosive or flammable products, such as fuel and fireworks, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Comfort really should be your main priority when choosing what to wear on your flight. Consider your footwear carefully too, as swollen feet and ankles are a common side effect of flying. Shoes which are flat and slightly roomy work well.
  • Unfortunately, a risk of flying long distances is developing deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To prevent this from happening, take every opportunity to walk around the cabin and stretch your legs. Compression tights and socks are also a great idea to help lower your risk.

How to get through airport security fast when flying to Boulder?
As seasoned travellers know, the secret is to be well prepared before you get to the security gate. That way, you’ll be hopping onto that plane to Boulder in the blink of an eye. Follow these helpful tips and get your trip off to a terrific start:

  • Be sure to keep your passport and travel documents handy. They’re the first things you’ll be asked to show at airport security.
  • Next up, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Personal belongings like your jacket, belt and headphones need to go through the machine.
  • All your electronic devices, including your laptop and phone, must also be scanned separately.
  • Remove all gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several minutes. Boots are often required to be removed and separately scanned. Slip-on shoes usually aren’t.
  • Airlines will not allow any sharp items or pocket knives in your hand luggage. If you need to bring these kinds of items, pack them in your checked baggage.
