Cheap Flights to Sierra Vista from HK$1,759

If you're not prepared, travelling can be tough. But don't hit the panic button just yet. Follow these helpful hints for a trouble-free start to your holiday in Sierra Vista. What to pack in your hand luggage:

• The trick to having a great travel experience is to plan ahead. So, let's start with the basics: passport, official ID, cash and daily medications. Next, bring on board items that'll help keep you busy, like your laptop or a good read. It's also wise to pack your chargers, a comfy neck pillow and a pair of earplugs. Last but not least, be sure to chuck in toiletries like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also prohibited.

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for temperature changes in the cabin by wearing layers, and pick closed-toe, flat shoes like slip-ons.
• Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-haul flights. Lower your risks by staying hydrated, keeping your ankles and legs moving and wearing compression socks to help improve your circulation.

A little pre-planning before you arrive at the airport will help make your trip to Sierra Vista a pleasure. We've compiled some handy tips and tricks for a stress-free journey through security:

• Keep your boarding pass and passport someplace easily accessible. They're the first items you'll be asked to present to airport security.
• The X-ray machine is up next. Remove anything metal on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• All your electronic gadgets, including your laptop and phone, are also required to be separately scanned.
• Any liquids or gels, such as hair oil or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
• The right choice of footwear can save you several valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on shoes are usually not.
• Pocket knives and other sharp items are not allowed on board. They'll be confiscated at security, so put them in your checked bags.
