How to survive the flight to Boulder?
Depending on where you’re coming from, your flight to Boulder could be as easy as pie or it could drag on forever. Here are some handy travel tips that will help you start your next unforgettable escape on a positive note.What to pack in your hand luggage:

  • Firstly, and most importantly, put in your passport, important documents, bank cards and vital medications. Next, you’ll need some in-flight entertainment to while away the hours. A juicy book and a tablet filled with your favourite shows are some great options. If you hope to take a quick nap, a quality neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a few toiletry items to ensure you hop off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don’t have sharp or pointed objects hiding in your carry-on luggage. Other prohibited items include explosive or flammable goods, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The narrow aisles of your plane are not the place for a fashion parade. Layer up with comfy clothing and remember to bring a sweater as it can get chilly inside the cabin. Flat, enclosed shoes are also a good choice.
  • You’ve probably heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. There’s lots you can do to lessen your risk. Don a pair of compression tights or socks, drink lots of water often and move your legs and feet. Wander up and down the aisles of the cabin or perform some stretches in your seat.

How to get through airport security fast when flying to Boulder?
Being prepared before you get to the airport can make your getaway to Boulder easy and painless. Check out our top tips for a swift journey past security:

  • Security personnel first need to make sure that you have a valid passport and boarding pass before you’re allowed to proceed any further. Have them within easy reach, ready for inspection.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes things like earphones or headphones, as well as bulky coats or jackets. They’ll need to be placed on the conveyor belt for screening.
  • Electronic devices like laptops and phones will also have to go through the machine to be scanned. No need to worry though, you’ll be back online before you know it.
  • Want to bring along your favourite perfume or cologne? No problem. As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a zip-close bag, you’re permitted to bring it with you on board.
  • Choosing your footwear wisely can save you valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won’t be allowed on board.
