• The secret to having a stress-free flight experience is to pack ahead. First up, the essentials: passport, travel docs, cash and any vital medications. Next, bring items that'll help keep you busy, like some electronic gadgets or a thrilling book. It's also smart to pack your chargers, a neck pillow and a pair of earphones. And of course, be sure to pop in toiletry items like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items can differ between air carriers, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, blades, spray paint and fireworks. Sporting equipment like baseball bats, and objects that could injure passengers, such as swords and batons, aren't allowed in the cabin either.

What to wear on a flight:

• Comfort really should be your priority when deciding what to wear during your flight. Consider your footwear choice carefully too, as swollen feet and ankles are a common side effect of flying. Flat shoes which are slightly roomy work well.
• Unfortunately, one risk of flying long distances is developing DVT (deep vein thrombosis), a blood clot condition caused by lengthy periods of inactivity. To prevent this, make the most of every opportunity to stretch your legs and walk around the cabin. Compression socks and tights are also a great idea to help reduce this risk.

As savvy travelers know, the secret is to be prepared before you get to airport security. That way, you'll be boarding that plane to San Juan in no time flat. Follow these helpful tips and get your trip off to a fantastic start:

• Security personnel first need to make sure that you have a valid ID and matching boarding pass before anything else. Have them in your hand, ready for inspection.
• Time to strip down. Well sort of. Your jacket, belt, keys and other items in your pocket, like coins, will be required to go through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
• Your electronic gadgets like laptops and phones will also have to go through the machine to be scanned. Don't worry though, you'll be back online in no time.
• Traveling with your favorite hand cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on.
• There's a possibility that you'll be required to take your shoes off for scanning, so wearing slip-on shoes is always a smart idea.
• Sharp items like knives are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked luggage.
