Cheap Flights to London from HK$5,398

If you're not prepared, traveling can be a real challenge. But there's no need to hit the panic button just yet. Follow these useful tips for a worry-free start to your time in London.What to pack in your hand luggage:

• Flying can be a comfortable experience if you pack the right things. Firstly, you'll need toiletry items, such as a toothbrush and lip balm, a spare set of clothes and a good book. Secondly, leave space in your bag for your phone, tablet and chargers, your medications and perhaps a cozy neck pillow as well. Lastly, be sure to take your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes box cutters, razor blades, aerosol cans and bleaching agents. Sports equipment like bows and arrows, and objects that could harm passengers, such as firearms and ammunition, can't come on board with you either.

What to wear on a flight:

• Your number one priority is to be as comfortable as possible. Layer up in breathable clothing and remember to bring a cardigan in case it gets cool. Opt for flat, well-fitting shoes as it's possible that your feet and ankles will swell a little during the journey. Leave the stilettos and hiking boots in your main luggage.
• The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a condition that can affect some passengers during long-haul flights. But the good news is there are proven ways to significantly reduce the risk of developing it. Keep your fluids up, get up and walk around the cabin whenever possible and wear compression tights or socks.

A little pre-planning before your flight will help make your trip to London a piece of cake. We've rounded up some useful tips for a speedy journey past security:

• Your travel documents and passport will need to be presented to airport security. Keep them at hand so you don't hold up the queue.
• Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
• Your electronic gadgets like phones and laptops will also have to go through the machine to be scanned. Don't worry, you'll be back online soon enough.
• Remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag.
• There's a possibility that you'll need to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a clever idea.
• Knives and other sharp items are not allowed in the cabin. They'll be seized at security, so put them in your checked baggage.
