Cheap Flights to Boulder from HK$1,355

We've rounded up all the info you need to make your flight a stress-free experience. Follow our tips and you'll be hightailing it through the airport and discovering Boulder in no time at all. What to pack in your hand luggage:

• Firstly, and most importantly, pack your passport, travel docs, cash and medications. Next, you'll need some in-flight entertainment to while away the time. A thrilling book and a tablet filled with your favourite shows are some great options. If you intend to catch a few z's, a neck pillow and a pair of earplugs will also come in handy. Finally, leave some space for a toothbrush and some facial wipes to ensure you touchdown feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between air carriers, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, blades, fuels and bleaching agents. Sporting equipment like golf clubs, and items that could harm passengers, such as swords and guns, won't be allowed on board either.

What to wear on a flight:

• Comfort should be your main concern when deciding what to wear on board. Loose, breathable clothing is a sensible choice, as are flat, enclosed shoes.
• Deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clots forming due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

The trick is to be well organised before you reach the security gate. That way, you'll be boarding that plane to Boulder in no time at all. Follow these helpful tips and get your holiday off to a fantastic start:

• Be sure to have your ID and boarding pass close by. They're the first items you'll be asked to present to security.
• Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items like your belt, coat and headphones need to go through the machine.
• For just a few moments, you'll have to unplug from technology. Your laptop, phone and any other electronic gadgets will need to be sent through the scanner.
• Travelling with a new hand and nail cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's fine to bring with you in your carry-on bag.
• Lightweight sneakers are a great footwear choice as you're less likely to be asked to remove them when passing through security. Safety boots and other heavy-style shoes are often subjected to extra screening.
• Airlines won't allow any sharp or pointed objects in your carry-on luggage. If you need to bring these kinds of items, check them in.
