So, let's start with the essentials: passport, boarding pass, credit cards and medications. Next, bring on board items that'll help keep you entertained, like your laptop or a thrilling novel. It's also wise to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. And of course, be sure to toss in toiletries like a toothbrush, cleansing wipes and a fresh set of clothes. > > > Do not pack the following items in your hand luggage: > > > - Double-check that you don't have a sharp object hiding in your carry-on luggage. Other banned items include explosive or flammable products, such as bleach and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Your main priority is to be as comfortable as you can. Opt for a pair of slip-on shoes, dress in loose, breathable clothing and remember to bring a sweater in case you get chilly in the cabin. > - Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Boulder? > - Security personnel first need to see that you have a valid passport and travel documents before anything else. Have them ready to show. > - The X-ray machine comes next. Remove anything metal on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets.

Big boots and heavier-style shoes are often subjected to additional screening. > - Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be seized at security, so pack them in your checked suitcase. __Flights to Boulder information__ | Destination airport | Kalgoorlie - Boulder | | ----------------------------- | -------------------- | | Destination airport IATA code | KGI | | Destination city name | Kalgoorlie - Boulder | | Roundtrip price | CA $503 | ## Trending flights to Boulder Prices were available within the past 7 days and start at CA $253 for one-way flights and CA $504 for round trip, for the period specified.
