Cheap Flights to Sero from HK$3,448

If you're poorly prepared, travelling can be testing. But there's no need to panic. Follow these handy hints for a pain-free start to your getaway in Sero. What to pack in your hand luggage:

• Air travel can be a comfortable experience if you take the right gear. First things first, you'll need basic toiletries, such as a toothbrush and lip balm, a clean set of clothes and something to read. Next, make room in your bag for your electronic devices, chargers, your important medications and maybe a comfy neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like a pocket knife, and dangerous products which are explosive or flammable, such as spray paint, flares and fireworks, are also not allowed.

What to wear on a flight:

• Your main priority is to be as comfortable as possible. Choose a pair of slip-on shoes, dress in loose, natural fibers and don't forget to take a jacket in case you get chilly in the cabin.
• Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To minimize your risk on board, stay hydrated, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

The answer is — be prepared. We've compiled some helpful hints for an easy trip through airport security. Look out Sero, here you come:

• Security personnel first need to verify that you have a valid passport and matching travel documents before you can proceed any further. Have them close by, ready for inspection.
• Time to strip down. Well sort of. Your belt, jacket, keys and other small items, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
• Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. Don't worry though, you'll be back online in no time.
• Any liquids or gels, such as perfume or hand cream, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
• Choosing your footwear wisely can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
• Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you must bring these kinds of items, put them in your checked luggage.
