Cheap Flights to Greenwich from HK$1,186

We've pulled together all the info you need to make your journey a stress-free experience. Follow our tips and you'll be hightailing it through airport security and enjoying Greenwich before you know it. What to pack in your hand luggage:

• Firstly, and most importantly, pack in your passport, important documents, credit cards and daily medications. Next, you'll want some extra in-flight entertainment to while away the hours. A juicy book and a laptop crammed with your favourite shows are some great options. If you intend to take a quick nap, a quality neck pillow and some noise-cancelling headphones will also be useful. Finally, squeeze in a toothbrush and some cleansing wipes so you'll hop off the plane feeling fresh as a daisy.

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 your hand luggage. Other restricted items include flammable or explosive goods, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• The aisles of an aircraft are no place for a fashion parade. Layer up with comfy clothing and opt for shoes that are flat, roomy and easy to take on and off.
• Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and keep your feet and legs moving.

The answer is — be prepared. We've compiled some tips and tricks for a speedy trip through security. Look out Greenwich, here you come:

• First things first. Your passport and boarding pass will need to be inspected by airport security. Keep them at hand so you don't have to dig around for them.
• Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items such as your belt, coat and earphones will be required to go through the machine.
• All your electronics, including your phone and tablet, will also need to be scanned separately.
• Remove all gels and liquids from your hand luggage. 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 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a sensible footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and other heavy-style shoes are often subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed on board.
