Cheap Flights to Heidelberg from HK$1,233

If you're poorly prepared, travelling can be tough. But there's no need to worry. Follow these useful tips for a comfortable start to your holiday in Heidelberg. What to pack in your hand luggage:

• Travelling on a plane can be a great experience if you take the right things. Firstly, you'll want a few basic toiletries, such as toothpaste, a toothbrush and some deodorant, a fresh change of clothes and a magazine or two. Secondly, make room in your carry-on bag for your laptop, a charger, medications and perhaps a proper neck pillow as well. Lastly, be sure to take your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your precious Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, chemicals agents and fireworks, are also prohibited.

What to wear on a flight:

• Comfort should be your main priority when choosing what to wear during your flight. Loose, breathable clothing is a wise choice, as are enclosed shoes like sneakers.
• The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long flights. Lower your risks by staying hydrated, keeping your legs and feet moving and wearing compression tights or socks.

It's all about being organised. We've compiled some top tips for a hassle-free trip through airport security. Look out Heidelberg, here you come:

• First things first. Your passport and boarding pass will need to be presented to airport security personnel. Have them close by to avoid fumbling around for them.
• The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
• For just a few moments, you'll need to unplug from the digital world. Your laptop, phone and any other electronic gadgets will need to go through the scanner.
• Travelling with your favourite hand and nail cream? No problem. As long as it's in a container no larger 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 luggage.
• It's also likely that you'll be required to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a smart idea.
• Pocket knives and other sharp items are prohibited in the cabin. They'll be confiscated at security, so put them in your checked luggage.
