Cheap Flights to Denver from HK$1,687

We've got the lowdown on how to make your journey a pleasant experience. Follow our tips and tricks and you'll be breezing through airport security and seeing the best of Denver in next to no time. What to pack in your hand luggage:

• Air travel can be a comfortable experience if you've got all the right gear. First of all you'll need basic toiletry items, such as a toothbrush and hairbrush, a spare change of clothes and a few magazines. Secondly, leave space in your bag for your phone, tablet and chargers, any vital medications and perhaps a blow-up neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

• While the list of restricted items can differ between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes things like knives, scissors, aerosol cans and bleaching agents. Sporting equipment like bows and arrows, and items that could injure passengers, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

• Your priority is to feel as comfortable as possible. Choose a pair of slip-on shoes, dress in loose, breathable clothing and don't forget to bring a jacket in case it gets cold in the cabin.
• Deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

Being organised before you arrive at the airport will make your getaway to Denver a pleasure. Read through our top tips for a speedy journey past security:

• Security personnel first need to check that you have a valid passport and travel documents before you're allowed to proceed any further. Keep them close by.
• The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
• All your electronics, including your phone and laptop, will also need to be separately scanned.
• Remember to remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
• It's also possible you'll need to take your shoes off for scanning, so wearing lightweight sneakers is always a smart idea.
• Airlines won't allow any sharp items or pocket knives in your carry-on luggage. If you need to bring these kinds of items, check them in.
