Cheap Flights to San Marcos from HK$1,903

If you're not prepared, air travel can be tough. But there's no need to worry. Follow these tips and tricks and enjoy a worry-free start to your getaway in San Marcos.What to pack in your hand luggage:

• The trick to having a stress-free travel experience is to pack ahead. So, let's start with the essentials: passport, travel docs, credit cards and vital medications. Next, take on board items that'll help while away those hours, like some electronic gadgets or a juicy novel. It's also a wise idea to bring your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to pop in toiletries like a toothbrush, cleansing wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a sharp object hiding in your carry-on luggage. Other banned items include flammable or explosive goods, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The answer to a comfortable flight can be as simple as your choice of clothing. Prepare for changes in temperature by layering up. This will keep you nice and warm if the cabin begins to cool down. Shoes like stilettos, flip flops and lace-up boots are best left in your checked suitcase. Even though they may be your favorites, go for flat, closed-toed footwear like slip-ons. Your feet will thank you later.
• Unfortunately, a risk of long-distance flying is developing deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To prevent this from happening, make the most of every opportunity to walk around the cabin and stretch your legs. Compression socks and tights are also a great idea to help minimize this risk.

The answer is — be prepared. We've compiled some helpful hints for a fuss-free trip through security. Look out San Marcos, here you come:

• Be sure to keep your ID and travel documents handy. They'll be the first things you'll be asked to present to airport security.
• Next up is the X-ray machine. Remove anything metal on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
• Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. Don't worry though, you'll be back online in no time.
• Don't forget to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-lock bag.
• Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other heavy-style shoes are often subjected to extra screening.
• Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be seized at security, so put them in your checked bags.
