Cheap Flights to Sierra Vista from HK$3,906

If you're not prepared, airports and flying can be challenging. But there's no need to worry. Follow these handy tips for a hassle-free start to your time in Sierra Vista.What to pack in your hand luggage:

• The trick to having a worry-free flight experience is to be prepared. So, let's start with the basics: passport, travel documents, cash and any vital medications. Next, take on board items that'll help pass the time, like your laptop or a few magazines. It's also wise to bring your chargers, a quality neck pillow and a pair of earplugs. Finally, don't forget to toss in toiletries like a toothbrush, deodorant and a spare set of clothes.

Do not pack the following items in your hand luggage:

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

What to wear on a flight:

• Comfort really should be your priority when picking what to wear during your flight. Consider your footwear choice with care too, as swollen ankles and feet are a common side effect of flying. Slightly roomy, flat shoes work well.
• Unfortunately, one risk of flying long distances is developing DVT (deep vein thrombosis), a blood clotting condition caused by lengthy periods of inactivity. To avoid this, take every opportunity to walk around the cabin and stretch your legs. Compression socks and tights are another simple way to help reduce this risk.

The trick is to be prepared before you reach security. That way, you'll be boarding that plane to Sierra Vista in no time flat. Follow these tips and get your trip off to a great start:

• Your travel documents and ID will need to be shown to airport security personnel. Keep them handy so you don't hold up the line.
• Time to strip down. Well kind of. Your jacket, belt, keys and other small items, like your headphones, will need to go through the X-ray machine. Make your life easier by removing them before your turn.
• Electronic devices like phones and laptops will also need to go on a tray for inspection. Don't worry, you'll be back online in no time.
• Any gels or liquids, such as toothpaste or perfume, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, they all must fit inside a quart-size (one liter), clear zip-close bag.
• It's also possible you'll need to take your shoes off to be X-rayed, so wearing slip-on shoes is always a clever idea.
• Airlines won't allow any sharp objects to come on board with you. If you must bring these kinds of items, pack them in your checked luggage.
