Cheap Flights to Knebworth from HK$1,990

If you're not prepared, airports and flying can be overwhelming. But there's no need to worry. Follow these handy hints for a comfortable start to your time in Knebworth.What to pack in your hand luggage:

• The trick to having a hassle-free travel experience is to pack in advance. Start with the essentials: passport, travel documents, bank cards and vital medications. Next, bring on board items that'll help keep you busy, like some electronic devices or a juicy novel. It's also a wise idea to pack your chargers, a neck pillow and a pair of earplugs. Last but not least, don't forget to squeeze in toiletry items like a toothbrush, facial wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a sharp object hiding in one of the zippers of your carry-on luggage. Other restricted items include flammable or explosive products, such as fuel and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The goal here is to feel as comfortable as possible. Dress in loose, natural-fiber clothing and remember to bring a jacket in case it gets cool in the cabin. Pick flat, slightly roomy shoes as it's possible that your feet and ankles will swell a little during the flight. Leave the high heels and chunky boots in your checked baggage.
• The result of lengthy periods of inactivity, DVT (deep vein thrombosis) is a condition that can affect some passengers during long-haul flights. The good news is there are proven ways to reduce the risk of developing it. Stay well hydrated, get up and wander the aisles as much as possible and wear compression tights or socks.

Being prepared before you arrive at the airport will help make your trip to Knebworth a pleasure. We've compiled some handy hints for a speedy journey past security:

• First things first. Your boarding pass and travel ID will need to be inspected by security personnel. Keep them handy to avoid fumbling around for them.
• The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
• All your electronics, including your phone and tablet, must also be scanned.
• Traveling with a new hand and nail cream? As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-close bag, it's OK to bring with you in your carry-on baggage.
• Choosing your footwear wisely can save you several precious minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
• Sharp items such as knives and scissors are prohibited in the cabin. They'll be confiscated at security, so pack them safely away in your checked luggage.
