Cheap Flights to San Francisco from HK$1,254

Depending on where you're coming from, your journey to San Francisco could be a breeze or it could go on forever. We've rounded up some handy travel tips that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

• The secret to having a pain-free flight experience is to be prepared. So, let's start with the essentials: passport, travel documents, credit cards and daily medications. Next, bring on board items that'll help keep you busy, like your laptop or a thrilling book. You'll also want to pack your chargers, a quality neck pillow and a pair of headphones. Finally, don't forget to pop in toiletries like a toothbrush, deodorant and a fresh set of clothes.

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) will be confiscated. Pointed or sharp objects, like your precious Swiss Army knife, and products which are explosive or flammable, such as spray paint, flares and gasoline, are also banned.

What to wear on a flight:

• Choose comfort over style. Prepare for temperature changes by layering up, and wear flat, easy-to-remove footwear like sneakers.
• The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long flights. Lower your risks by drinking water, keeping your ankles and legs moving and wearing compression socks to help your circulation.

The answer is simple — be organised. We've pulled together some useful tips for a fuss-free trip through airport security. Watch out San Francisco, here you come:

• Keep your travel documents and passport handy. They're the first things you'll be asked for by airport security.
• The X-ray machine is up next. Remove anything on you that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• Electronic devices like laptops and phones will also have to go on a tray to be scanned. Don't worry though, you'll be back online soon enough.
• Can't travel without your favourite perfume or cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you in your carry-on.
• The right choice of footwear can save you several valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked baggage. They won't be allowed on board.
