Cheap Flights to Serina from HK$421

If you're not prepared, airports and flying can be challenging. But don't hit the panic button just yet. Follow these handy hints for a stress-free start to your time in Serina.What to pack in your hand luggage:

• The trick to having an awesome travel experience is to pack in advance. First up, the essentials: passport, official ID, bank cards and important medications. Next, take on board items that'll help keep you entertained, like some electronic devices or a magazine. It's also a wise idea to bring your chargers, a neck pillow and a pair of headphones. And of course, don't forget to toss in toiletry items like a toothbrush, deodorant and a clean set of clothes.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between airlines, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes things like knives, scissors, fireworks and fuel. Sporting equipment like baseball bats, and objects that could injure passengers, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

• Your goal here is to be as comfortable as possible. Layer up in natural fibers and pack a sweater just in case you get chilly. Go for a pair of flat, slightly roomy shoes as your feet may swell a little during the journey. Leave the high heels and heavy boots in your luggage.
• Caused by sustained periods of immobility, DVT (deep vein thrombosis) is a blood clotting condition that can affect some passengers during long-haul flights. But the great news is there are proven ways to lower your risk of developing it. Stay hydrated, get up and walk around the cabin as often as possible and wear compression socks or tights.

Being organized before you get to the airport will help make your trip to Serina easy and painless. Check out our handy tips and tricks for a swift journey through security:

• Have your passport and travel documents within easy reach. They're the first items you'll be asked to present to airport security.
• Next up is the X-ray machine. Remove anything metal on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
• For just a few minutes, you'll have to unplug from the digital world. Your phone, laptop and any other electronic gadgets also need to be sent through the scanner.
• Remember to remove gels and liquids from your carry-on bag. 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 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
• Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when passing through security. Boots and other heavy shoes are usually subjected to extra screening.
• Airlines won't allow any sharp or pointed objects in the cabin. If you must bring these kinds of items, put them in your checked luggage.
