Cheap Flights to San Juan from HK$658

We've got the lowdown on how to make your flight as enjoyable as possible. Follow our tips and you'll be zooming through the airport and enjoying San Juan in no time.What to pack in your hand luggage:

• The secret to having a pain-free travel experience is to be prepared. First up, the essentials: passport, boarding pass, cash and daily medications. Next, bring on board items that'll help keep you occupied, like some electronic devices or a juicy novel. You'll also want to bring your chargers, a quality neck pillow and a pair of earplugs. Last but not least, be sure to toss in toiletry items like a toothbrush, deodorant and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Pointed or sharp objects, like your trusty Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, bleaching agents and fuels, are also not allowed.

What to wear on a flight:

• Your goal here is to make yourself as comfortable as you can. Layer up in breathable clothing and pack a cardigan just in case you get chilly. Go for a pair of well-fitting, flat shoes as it's possible that your feet and ankles will swell during the journey. Leave the stilettos and chunky boots in your luggage.
• Most travelers have heard about DVT (deep vein thrombosis), a blood clotting condition caused by reduced mobility or inactivity. There are many ways to minimize your risk. Wear a good-quality pair of compression tights or socks, stay hydrated and keep your legs and feet moving. Walk around the cabin when possible or try out some simple stretches in your seat.

The simple answer is — be prepared. We've rounded up some top tips for a stress-free trip through security. Watch out San Juan, here you come:

• Your ID and travel documents will need to be presented to airport security personnel. Keep them within easy reach to avoid fumbling around for them.
• Next up, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Items such as your jacket, belt and earphones will be required to go through the machine.
• Your electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
• Traveling with your favorite hand cream? As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-close bag, you're permitted to bring it with you in your carry-on.
• Slip-on shoes are a clever footwear choice as you're less likely to be required to remove them when going through security. Safety boots and other heavy shoes are often subjected to additional screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed on board and will be confiscated.
