Cheap Flights to Thermopolis from HK$4,106

If you're poorly prepared, airports and flying can be testing. But there's no need to panic. Follow these helpful hints and enjoy a comfortable start to your time in Thermopolis. What to pack in your hand luggage:

• Firstly, and most importantly, put in your passport, official ID, wallet and medications. Next, you'll want some extra in-flight entertainment to while away the hours. A thrilling book and a tablet filled with your favourite shows are some great options. If you hope to take a quick snooze, a neck pillow and some noise-cancelling headphones will also come in handy. Finally, make room for a toothbrush and some cleansing wipes to ensure you arrive looking fresh and ready to go.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your treasured pocket knife, and dangerous products which are flammable or explosive, such as aerosol cans, spray paint and fuels, are also not allowed.

What to wear on a flight:

• Your main aim is to be as comfortable as possible. Go for shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and remember to bring a jacket in case it gets cold in the cabin.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lower your risk on board, stay hydrated, consider wearing compression socks and move your lower limbs often.

The secret is to be well organised before you arrive at security. That way, you'll be boarding that plane to Thermopolis in no time at all. Follow these helpful tips and get your trip off to a spectacular start:

• First things first. Your boarding pass and passport will need to be shown to security personnel. Have them easily accessible so you don't hold up the queue.
• The X-ray machine comes next. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• All electronic gadgets, including your laptop and phone, are also required to be scanned.
• Any gels or liquids, such as hair oil or hand cream, 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 great footwear choice as you're less likely to be asked to remove them when passing through security. Hiking boots and other bulky shoes are usually subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked baggage. They won't be allowed in the cabin.
