Cheap Flights to Kärkölä from HK$3,717

Depending on where you're coming from, your trip to Kärkölä could be simple and straightforward or it could go on forever. Below are some useful tips that will help you start your next great adventure on the right foot. What to pack in your hand luggage:

• The trick to having a pain-free travel experience is to plan ahead. First up, the essentials: passport, travel documents, credit cards and daily medications. Next, bring on board items that'll help keep you entertained, like some electronic gadgets or a few magazines. It's also smart to bring your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Last but not least, be sure to chuck in toiletry items like a toothbrush, facial wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

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

What to wear on a flight:

• The aisles of an aircraft aren't the place for a fashion parade. Layer your clothing and pick shoes that are flat, roomy and easy to remove.
• Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clots forming due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

Being organised before you get to the airport will make your trip to Kärkölä a piece of cake. Check out our handy tips for a stress-free journey through security:

• Your travel documents and ID will need to be inspected by airport security personnel. Keep them at hand so you don't have to dig around for them.
• Time to strip down. Well kind of. Your belt, coat, keys and other small items, like your headphones, will be required to go through the X-ray machine. Make the whole process faster by removing them as your turn draws near.
• All your electronic devices, including your tablet and phone, are also required to be scanned.
• Remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
• Slip-on shoes are a good footwear choice as you're less likely to have to remove them when going through security. Safety boots and other heavy-style shoes are usually subjected to additional screening.
• Sharp or pointed items are prohibited in the cabin. They'll be confiscated at security, so pack them safely away in your checked bags.
