Cheap Flights to Big Sky from HK$899

We've pulled together all the info you need to make your flight a stress-free experience. Follow our top tips and you'll be zooming through airport security and exploring Big Sky in no time. What to pack in your hand luggage:

• The trick to having a great travel experience is to plan ahead. First up, the essentials: passport, official ID, cash and any vital medications. Next, bring items that'll help while away those hours, like some electronic devices or a magazine. It's also wise to bring your chargers, a neck pillow and a pair of headphones. Last but not least, don't forget to squeeze in toiletries like a toothbrush, facial wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your beloved Swiss Army knife, and products which are flammable or explosive, such as flares, chemicals agents and fireworks, are also restricted.

What to wear on a flight:

• Choose comfort over style. Prepare for changes in temperature by dressing in layers, and opt for slightly roomy, flat footwear like slip-ons.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lessen your risk on board, drink plenty of water, consider wearing compression tights or socks and keep your legs and feet moving.

As seasoned travellers know, the secret is to be well organised before you reach security. That way, you'll be stepping onto that plane to Big Sky before you know it. Follow these tips and get your holiday off to a terrific start:

• Security personnel first need to establish that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them in your hand, ready for inspection.
• After that, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Items such as your belt, coat and headphones need to go through the machine.
• Your electronic devices like laptops and phones will also have to go on a tray to be scanned. No need to worry though, you'll be back online before you know it.
• Any gels or liquids, 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, everything must fit inside a quart-size (one litre), clear zip-lock bag.
• There's a good chance you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a clever idea.
• Sharp or pointed items are not allowed on board. They'll be seized at security, so put them in your checked baggage.
