Cheap Flights to Mettmann from HK$3,873

We've got the lowdown on how to make your journey a pleasant experience. Follow our tips and you'll be breezing through airport security and enjoying Mettmann in next to no time. What to pack in your hand luggage:

• First and foremost, pack your passport, travel documents, wallet and medications. Next, you'll need some entertainment to help pass the time. A thrilling novel and a tablet crammed with your favourite shows are some terrific options. If you hope to take a quick snooze, a quality neck pillow and some noise-cancelling headphones will also be useful. Finally, squeeze in a toothbrush and some facial wipes so you'll arrive at your destination feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like your trusty pocket knife, and products which are explosive or flammable, such as flares, chemicals agents and fuels, are also banned.

What to wear on a flight:

• Your main aim is to feel as comfortable as possible. Pick slip-on footwear, dress in loose, breathable clothing and don't forget to bring a pullover in case it gets cold in the cabin.
• The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Reduce the risks by staying hydrated, keeping your legs and feet moving and wearing compression tights or socks.

The secret is to be well prepared before you reach the airport security gate. That way, you'll be hopping onto that plane to Mettmann in a flash. Follow these tips and get your trip off to a great start:

• Your travel ID and boarding pass will need to be presented to security personnel. Keep them at hand so you don't have to dig around for them.
• After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Items like your jacket, belt and headphones need to go through the machine.
• Your electronic gadgets like laptops and phones will also have to go through the machine for inspection. Don't worry though, you'll be back online before you know it.
• Travelling with a new perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're permitted to bring it with you in your carry-on.
• There's a chance you'll be required to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a good idea.
• Airlines won't allow any pocket knives or other sharp items in the cabin. If you need to bring these kinds of items, check them in.
