Cheap Flights to San Juan from HK$1,690

Depending on where you're coming from, your journey to San Juan could be a piece of cake or it could go on forever. Below are some useful hints that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

• First of all, put in your passport, travel docs, credit cards and daily medications. Next, you'll need some entertainment to while away the hours. A juicy book and a tablet filled with your favourite shows are some wonderful options. If you hope to take a short nap, a neck pillow and a pair of earplugs will also be useful. Finally, make room for a toothbrush and some facial wipes to ensure you arrive at your destination looking fresh and ready to go.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like a pocket knife, and dangerous products which are flammable or explosive, such as aerosol cans, spray paint and poisons, are also restricted.

What to wear on a flight:

• Go for comfort over style. Prepare for changes in temperature by donning layers, and opt for flat, slightly roomy footwear like sneakers.
• Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs and ankles moving and wearing compression tights or socks.

The answer is simple — be organised. We've rounded up some helpful hints for a stress-free trip through airport security. Look out San Juan, here you come:

• Keep your travel documents and ID close by. They'll be the first things you'll be asked to show at airport security.
• Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn.
• All your electronics, including your phone and laptop, will also need to be scanned.
• Any gels or liquids, such as perfume or hand cream, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
• Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when passing through security. Boots and other bulky shoes are often subjected to additional screening.
• Airlines will not allow any pocket knives or other sharp items in your carry-on luggage. If you need to bring these kinds of items, pack them safely in your checked luggage.
