Cheap Flights to Greenwich from HK$1,383

We've got the lowdown on how to make your flight as enjoyable as possible. Follow our tips and tricks and you'll be cruising through airport security and exploring Greenwich before you know it. What to pack in your hand luggage:

• The trick to having a hassle-free flight experience is to pack in advance. Start with the essentials: passport, official ID, credit cards and vital medications. Next, bring on board items that'll help while away those hours, like some electronic gadgets or a thrilling book. It's also smart to bring your chargers, a comfy neck pillow and a pair of earphones. Last but not least, be sure to pop in toiletries like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

• Double-check that you don't have sharp objects (like a pocket knife) hiding in one of the zippers of your carry-on luggage. Other prohibited items include flammable or explosive substances, such as fuel and fireworks, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Your goal here is to be as comfortable as possible. Opt for flat, closed-toe shoes, dress in loose, natural fibers and don't forget to take a sweater in case you get chilly in the cabin.
• Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To reduce your risk on board, drink plenty of water, consider wearing compression socks and move your lower limbs often.

Being organised before you get to the airport can make your trip to Greenwich quick and painless. Below are some handy hints for a swift journey past security:

• Airport security personnel first need to check that you have a valid passport and matching boarding pass before anything else. Keep them close by.
• The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• All your electronic devices, including your phone and laptop, are also required to be separately scanned.
• Can't travel without your favourite perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's fine to bring with you in your carry-on bag.
• Lightweight sneakers are a clever footwear choice as you're less likely to be required to remove them when passing through security. Boots and other heavy shoes are usually subjected to additional screening.
• Sharp items are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked suitcase.
