Cheap Flights to Varna from HK$2,157

Depending on where you're coming from, your journey to Varna could be a breeze or it could go on forever. We've rounded up some useful tips that will help you start your next big adventure on a positive note.What to pack in your hand luggage:

• The secret to having a worry-free travel experience is to pack in advance. Start with the essentials: passport, travel docs, bank cards and daily medications. Next, bring items that'll help while away those hours, like some electronic gadgets or a thrilling book. You'll also want to bring your chargers, a neck pillow and a pair of earplugs. And of course, don't forget to toss in toiletry items like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a Swiss Army knife lurking in the bottom of your hand luggage. Other banned items include explosive or flammable substances, such as fuel and matches, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The aisles of an aircraft are not the place for a fashion parade. Layer up with comfy clothing and pack a cardigan as it tends to get cool inside the cabin on long-haul flights. Slightly roomy, flat shoes are also a wise idea.
• The serious condition by the name of DVT (deep vein thrombosis) can pose a risk on long-haul flights. It's the result of blood clotting due to poor circulation. Walking around the cabin and doing regular leg and foot exercises in your seat helps to prevent this from occurring. Wearing a pair of compression socks also helps reduce your risk.

The answer is simple — be organized. We've pulled together some tips and tricks for a hassle-free trip through security. Watch out Varna, here you come:

• Airport security personnel first need to verify that you have a valid passport and boarding pass before you're allowed to proceed any further. Keep them close by.
• After that, both you and your hand luggage must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items such as your jacket, belt and earphones will be required to go through the machine.
• For just a few minutes, you'll need to unplug from the digital world. Your phone, laptop and any other electronic gadgets must also be sent through the scanner.
• Traveling with your favorite cologne or perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you're allowed to bring it with you on board.
• There's a chance you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a good idea.
• Pocket knives and other sharp items are not allowed on board. They'll be seized at security, so pack them in your checked luggage.
