Cheap Flights to Trossingen from HK$3,542

If you're poorly prepared, air travel can be overwhelming. But there's no need to panic. Follow these useful tips for a stress-free start to your time in Trossingen.What to pack in your hand luggage:

• The trick to having a worry-free travel experience is to plan ahead. So, let's start with the basics: passport, official ID, bank cards and important medications. Next, bring on board items that'll help keep you busy, like your laptop or a juicy novel. It's also smart to pack your chargers, a quality neck pillow and a pair of earplugs. Last but not least, be sure to pop in toiletries like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• Make sure you don't have a Swiss Army knife hiding in one of the compartments of your carry-on luggage. Other prohibited items include flammable or explosive goods, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

• Comfort should always be the goal when picking what to wear on your flight. Consider your footwear with care too, as swollen feet and ankles are quite common. Flat, slightly roomy shoes are your best bet.
• A condition known as DVT (deep vein thrombosis) can pose a risk on long-haul flights. It's the result of blood clots forming due to inactivity and poor circulation. Walking up and down the aisle and doing foot and leg exercises in your seat is a great way to prevent this developing. Wearing a pair of compression tights or socks also helps reduce the risk.

A little pre-planning before you get to the airport will help make your trip to Trossingen a piece of cake. We've rounded up some top tips for a speedy journey past security:

• Keep your passport and travel documents at hand. They're the first things you'll be asked to present to airport security.
• Your coat, belt, keys and other small items, like your earphones, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn.
• Your electronic devices like laptops and phones will also have to go on a tray to be scanned. Don't worry, you'll be back online before you know it.
• Any liquids or gels, such as hair oil or hand cream, that you want to bring on board must be no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-lock bag.
• There's a good chance you'll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a wise idea.
• Pocket knives and other sharp items are not allowed in the cabin. They'll be confiscated at security, so pack them in your checked baggage.
