Cheap Flights to San Marcos from HK$4,300

Depending on where you're coming from, your flight to San Marcos could be completely stress-free or it could drag on forever. We've compiled some tips that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

• First and foremost, pack in your passport, official ID, bank cards and daily medications. Next, you'll want some in-flight entertainment to while away the time. A thrilling novel and a laptop crammed with your favourite shows are some fantastic options. If you plan to take a quick nap, a neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a few toiletry items so you'll hop off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

• While the list of prohibited items can differ between air carriers, the general rule to follow is nothing flammable, sharp or explosive. This includes screwdrivers, blades, fuel and fireworks. Sporting equipment like ski poles, and items that could harm other people, such as swords and batons, aren't allowed in the cabin either.

What to wear on a flight:

• The aisles of an airplane are no place for a fashion parade. Dress in comfortable layers and choose shoes that are flat, roomy and easy to take on and off.
• Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to promote better circulation.

It's simple — be prepared. We've put together some tips and tricks for an easy trip through airport security. Look out San Marcos, here you come:

• Have your passport and travel documents someplace easily accessible. They're the first items you'll be asked for by airport security.
• Next up, both you and your hand luggage will be X-rayed. To speed things up, remove anything that might trigger the alarms. Items like your belt, jacket and headphones need to go through the machine.
• All your electronic devices, including your tablet and phone, are also required to be scanned.
• Want to bring along your favourite perfume or cologne? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on.
• There's a chance you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a clever idea.
• Sharp or pointed objects (like knives and scissors) are not allowed on board. They'll be seized at security, so put them in your checked bags.
