We've pulled together all the info you need to make your flight a stress-free experience. Follow our insider tips and you'll be speeding through the airport and discovering San Juan in no time flat. What to pack in your hand luggage:

• The secret to having a pain-free travel experience is to pack in advance. So, let's start with the basics: passport, boarding pass, bank cards and any vital medications. Next, take on board items that'll help while away those hours, like some electronic devices or a thrilling book. It's also wise to bring your chargers, a comfy neck pillow and a pair of headphones. And of course, be sure to pop in toiletries like a toothbrush, deodorant and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a Swiss Army knife hiding in the bottom of your carry-on luggage. Other prohibited items include explosive or flammable substances, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Choose comfort over style. Prepare for changes in cabin temperature by wearing layers, and opt for closed-toe, flat footwear like sneakers.
• The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Reduce the risks by drinking water, keeping your feet and legs moving and wearing compression socks to help your circulation.

The secret is to be well organised before you get to the security gate. That way, you'll be stepping onto that plane to San Juan in a flash. Follow these tips and get your trip off to a fantastic start:

• First things first. Your boarding pass and travel ID will need to be shown to airport security personnel. Keep them someplace accessible to avoid fumbling around for them.
• Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• All your electronic gadgets, including your phone and laptop, are also required to be separately scanned.
• Can't travel without your favourite hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on.
• Choosing your footwear wisely can save you a few precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Lightweight sneakers are usually not.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked baggage. They won't be allowed on board.
