We've got the lowdown on how to make your flight a pleasant experience. Follow our tips and tricks and you'll be speeding through airport security and having a ball in Boulder in next to no time. What to pack in your hand luggage:

• The trick to having a hassle-free travel experience is to be prepared. 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.

Being prepared before your flight will help make your getaway to Boulder a piece of cake. We've compiled some useful tips and tricks for a speedy journey through security:

• 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. They'll all need to go on the X-ray conveyor belt.
• All electronic gadgets, including your phone and laptop, are also required to be separately scanned.
• Any liquids or gels, such as lip balm or cologne, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
• Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when passing through security. 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.
