Cheap Flights to Heathrow from HK$703

If you're poorly prepared, airports and flying can be challenging. But don't hit the panic button just yet. Follow these tips and tricks and enjoy a trouble-free start to your holiday in Heathrow. What to pack in your hand luggage:

• First and foremost, pack in your passport, important documents, credit cards and daily medications. Next, you'll want some entertainment to while away the time. A thrilling book and a tablet crammed with your favourite movies are good options. If you hope to catch up on some sleep, a comfy neck pillow and a pair of earplugs will also be useful. Finally, leave some space for a few toiletry items so you'll arrive looking fresh and raring to go.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your beloved Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, bleaching agents and fuels, are also prohibited.

What to wear on a flight:

• Your top priority is to be as comfortable as possible. Opt for a pair of flat, closed-toe shoes, dress in loose, breathable clothing and remember to bring a pullover in case you get cold in the cabin.
• You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To lower your risk on board, drink plenty of water, consider wearing compression tights or socks and keep your legs and feet moving.

The secret is to be well organised before you arrive at security. That way, you'll be stepping onto that plane to Heathrow in next to no time. Follow these helpful tips and get your holiday off to a great start:

• Airport security personnel first need to check that you have a valid passport and boarding pass before you're allowed to proceed any further. Have them ready to show.
• Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Items like your jacket, belt and earphones need to go through the machine.
• Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online before you know it.
• Remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a practical footwear choice as you're less likely to be asked to remove them when going through security. Big boots and other heavy shoes are usually subjected to additional screening.
• Airlines will not allow any sharp or pointed objects to come on board with you. If you must bring these kinds of items, pack them in your checked luggage.
