Cheap Flights to Castro from HK$5,610

We've got the lowdown on how to make your flight as stress-free as possible. Follow our insider tips and you'll be zooming through the airport and exploring Castro in no time.What to pack in your hand luggage:

• The secret to having an awesome travel experience is to pack ahead. So, let's start with the basics: passport, official ID, credit cards and important medications. Next, bring items that'll help keep you entertained, like your laptop or a magazine. It's also wise to pack your chargers, a comfy neck pillow and a pair of headphones. And of course, be sure to toss in toiletries like a toothbrush, lip balm and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp or pointed objects, like your Swiss Army knife, and dangerous products which are explosive or flammable, such as aerosol cans, spray paint and poisons, are also banned.

What to wear on a flight:

• The best way to ensure a comfortable flight is often as simple as your choice in clothes. Prepare for changes in temperature by layering up. That way you'll stay nice and warm if the cabin starts to cool down. Shoes like sandals and heels are best left in your checked suitcase. Even though they may be your favorites, go for flat, closed-toed footwear like sneakers. Your feet will thank you later.
• A condition called deep vein thrombosis (DVT) can pose a risk on long-distance flights. It's the result of blood clots forming due to poor circulation. Walking up and down the aisle and doing foot and leg exercises in your seat helps to prevent this occurring. Wearing a good pair of compression socks or tights is also recommended.

It's easy — be prepared. We've rounded up some top tips for a hassle-free trip through security. Watch out Castro, here you come:

• Your travel documents and passport will need to be inspected by security personnel. Keep them within easy reach so you don't hold up the line.
• Your belt, jacket, keys and other items in your pocket, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them before your turn arrives.
• For just a few moments, you'll need to unplug from the digital world. Your phone, laptop and any other electronics must also be sent through the scanner.
• Remember to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-lock bag.
• Slip-on shoes are a great footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and other heavy shoes are usually subjected to extra screening.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed in the cabin.
