Cheap Flights to Hertford from HK$1,738

If you're poorly prepared, airports and flying can be a real challenge. But there's no need to hit the panic button just yet. Follow these tips and tricks for a hassle-free start to your time in Hertford. What to pack in your hand luggage:

• First, pack your passport, important documents, bank cards and medications. Next, you'll need some extra in-flight entertainment to while away the time. A juicy book and a laptop crammed with your favourite shows are some fantastic options. If you hope to take a short nap, a quality neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a toothbrush and some facial wipes to ensure you touchdown feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

• While the list of restricted items can differ between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes screwdrivers, drills, fireworks and fuel. Sporting equipment like ski poles, and objects that could harm passengers, such as pepper spray and firearms, won't be allowed on board either.

What to wear on a flight:

• Comfort should be your top priority when choosing what to wear on your flight. Loose, breathable clothing is a smart option, as are flat, slip-on shoes.
• Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clots forming due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

It's all about being organised. We've pulled together some tips and tricks for an easy trip through security. Look out Hertford, here you come:

• Have your travel documents and passport within easy reach. They're the first items you'll be asked to present to airport security.
• The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
• For just a few moments, you'll need to unplug from the digital world. Your laptop, phone and any other electronic gadgets will need to go through the scanner.
• Travelling with a new hand and nail cream? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's OK to bring with you in your carry-on bag.
• Slip-on shoes are a practical footwear choice as you're less likely to be asked to remove them when going through security. Boots and other heavy shoes are often subjected to additional screening.
• Sharp or pointed objects (like knives and scissors) can't be taken on board. They'll be seized at security, so put them in your checked suitcase.
