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

• The secret to having a great flight experience is to pack in advance. First up, the essentials: passport, travel docs, cash and important medications. Next, take on board items that'll help pass the time, like your laptop or a good book. You'll also want to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to pop in toiletry items like a toothbrush, deodorant and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Make sure you don't have a Swiss Army knife lurking in the bottom of your hand luggage. Other banned items include flammable or explosive goods, like aerosols and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• The aisles of an airplane are no place for a fashion parade. Layer up with comfortable clothing and opt for shoes that are roomy, flat and easy to pull on and off.
• Most travellers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and move your lower limbs often.

Being prepared before you arrive at the airport will help make your getaway to Denver a piece of cake. Here are some useful tips and tricks for a stress-free journey through security:

• Security personnel first need to check that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
• Time to strip down. Well kind of. Your jacket, belt, keys and other items in your pocket, like coins, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn.
• All electronic devices, including your phone and laptop, are also required to be scanned.
• Don't forget to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a great footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and other heavy shoes are usually subjected to additional screening.
• Pocket knives and other sharp items are not allowed in the cabin. They'll be confiscated at security, so put them in your checked bags.
