We've rounded up all the info you need to make your journey an enjoyable experience. Follow our top tips and you'll be hightailing it through the airport and seeing the best of Greenwich in no time at all.What to pack in your hand luggage:

• First of all, put in your passport, important documents, bank cards and medications. Next, you'll want some in-flight entertainment to while away the hours. A juicy book and a phone filled with your favorite movies are always good options. If you hope to catch up on some sleep, a neck pillow and some earplugs will also be useful. Finally, make room for a toothbrush and some facial wipes to ensure you touchdown feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

• While the list of restricted items can differ between airlines, the general guide to follow is nothing sharp, flammable or explosive. This includes screwdrivers, pocket knives, spray paint and flares. Sporting equipment like ski poles, and objects that could harm passengers, such as swords and guns, aren't allowed in the cabin either.

What to wear on a flight:

• The long, narrow aisles of your airplane are no fashion runway. Layer up with comfy clothing and don't forget to bring a sweater as it can get chilly in the cabin on long-haul flights. Slightly roomy, flat shoes are also recommended.
• The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-haul flights. But the good news is there are ways to significantly reduce your risk of developing it. Stay hydrated, get up and walk around the cabin whenever possible and wear compression socks or tights.

It's all about being organized. We've put together some top tips for an easy trip through security. Watch out Greenwich, here you come:

• Airport security personnel first need to see that you have a valid ID and travel documents before anything else. Have them ready for inspection.
• Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Personal belongings like your belt, jacket and earphones will be required to go through the machine.
• Your 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 before you know it.
• Remember to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one liter), clear zip-lock bag.
• There's a chance you'll be required to take your shoes off for scanning, so wearing lightweight sneakers is always a good idea.
• Airlines will not allow any sharp items or pocket knives in your carry-on baggage. If you need to bring these kinds of items, put them in your checked baggage.
