Cheap Flights to Opatija from HK$840

If you're poorly prepared, traveling can be testing. But don't hit the panic button just yet. Follow these handy tips for a comfortable start to your vacation in Opatija.What to pack in your hand luggage:

• The secret to having a hassle-free flight experience is to plan ahead. So, let's start with the essentials: passport, boarding pass, bank cards and medications. Next, bring items that'll help keep you occupied, like your laptop or a magazine. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of noise-canceling headphones. And of course, don't forget to squeeze in toiletry items like a toothbrush, facial wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

• Double-check that you don't have sharp or pointed objects lurking in the bottom of your hand luggage. Other prohibited items include explosive or flammable substances, such as fuel and matches, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The aisles of your aircraft are not the place for a fashion parade. Don comfortable layers and take a sweater as it tends to get cool inside the cabin during long-haul flights. Slightly roomy, flat shoes are always a good idea too.
• A 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 and inactivity. Doing regular leg and foot exercises while seated is a great way to prevent this developing. Wearing a high-quality pair of compression tights or socks also helps reduce the risk.

The answer is simple — be organized. We've pulled together some useful tips for an easy trip through security. Look out Opatija, here you come:

• Airport security personnel first need to make sure that you have a valid ID and travel documents before you're allowed to proceed any further. Have them ready to show.
• Next up is the X-ray machine. Empty your pockets and remove anything that is likely to beep. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
• Your electronic gadgets like laptops and phones will also need to go on a tray for inspection. Don't worry though, you'll be back online before you know it.
• Want to bring along your favorite cologne or perfume? As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on luggage.
• The right choice of footwear can save you several valuable minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on shoes are usually not.
• Sharp or pointed objects (like knives and scissors) can't be taken on board. They'll be confiscated at security, so pack them in your checked luggage.
