Cheap Flights to Greenwich from HK$3,379

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

• First and foremost, pack in your passport, official ID, credit cards and daily medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling book and a laptop crammed with your favorite shows are some terrific options. If you intend to catch up on some sleep, a comfy neck pillow and some noise-canceling headphones will also come in handy. Finally, squeeze in a toothbrush and some deodorant so you'll touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

• Double-check that you don't have sharp objects (like a knife or scissors) lurking in one of the zippers of your hand luggage. Other restricted items include explosive or flammable products, such as bleach and fuel, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The long, narrow aisles of an aircraft are not the place for a fashion parade. Layer up with comfy clothing and take a cardigan as it can get chilly inside the cabin during long-haul flights. Flat, enclosed shoes are also recommended.
• Unfortunately, one risk of long-haul flights is developing DVT (deep vein thrombosis), a blood clot condition caused by lengthy periods of inactivity. To prevent this, take every opportunity to walk around and give your legs a stretch. Compression socks and tights are another great idea to help minimize this risk.

It's easy — be prepared. We've put together some top tips for a hassle-free trip through security. Watch out Greenwich, here you come:

• Security personnel first need to determine that you have a valid passport and matching boarding pass before you can proceed any further. Have them ready for inspection.
• After that, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that might trigger the alarms. Items such as your coat, belt and headphones will be required to go through the machine.
• Electronic devices like phones and laptops will also have to go through the machine to be scanned. No need to worry though, you'll be back online in no time.
• Don't forget to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one liter), clear zip-close bag.
• The right choice of footwear can save you a few precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
• Sharp items like knives are not allowed in the cabin. They'll be confiscated at security, so pack them in your checked suitcase.
