We've pulled together all the info you need to make your flight as enjoyable as possible. Follow our insider tips and you'll be hightailing it through airport security and having a blast in San Francisco in no time. What to pack in your hand luggage:

• The secret to having a stress-free travel experience is to be prepared. Start with the essentials: passport, travel documents, cash and important medications. Next, bring items that'll help while away those hours, like your laptop or a magazine. You'll also want to pack your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. And of course, don't forget to pop in toiletries like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and hairspray in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like a Swiss Army knife, and dangerous products which are flammable or explosive, such as spray paint, flares and fuels, are also not allowed.

What to wear on a flight:

• Comfort should be your highest priority when deciding what to wear on your flight. Loose, breathable clothing is a smart choice, as are flat, closed-toe shoes.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to promote better circulation.

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

• First things first. Your travel ID and boarding pass will need to be presented to airport security. Keep them someplace accessible so you don't have to dig around for them.
• Your belt, jacket, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn.
• Your electronic gadgets like laptops and phones will also have to go through the machine to be scanned. Don't worry, you'll be back online soon enough.
• Want to bring along your favourite perfume? 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 fine to bring with you in your carry-on baggage.
• It's also possible you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a wise idea.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed on board.
