Cheap Flights to San Clemente from HK$439

If you're poorly prepared, air travel can be tough. But there's no need to worry. Follow these helpful hints and enjoy a trouble-free start to your time in San Clemente. What to pack in your hand luggage:

• The secret to having a worry-free travel experience is to pack in advance. Start with the essentials: passport, official ID, cash and any vital medications. Next, bring items that'll help pass the time, like some electronic gadgets or a good read. It's also wise to pack your chargers, a quality neck pillow and a pair of headphones. Last but not least, don't forget to pop in toiletry items like a toothbrush, lip balm and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes screwdrivers, pocket knives, fuels and bleaching agents. Sports equipment like golf clubs, and items that could injure passengers, such as pepper spray and firearms, are also banned from the cabin.

What to wear on a flight:

• Your priority is to be as comfortable as you can. Pick shoes that are easy to pull on and off, dress in loose, breathable clothing and don't forget to bring a jacket in case it gets cold in the cabin.
• Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It results from blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

Being organised before you arrive at the airport will make your trip to San Clemente a breeze. Read through our handy tips for a speedy journey through security:

• Airport security personnel first need to determine that you have a valid ID and travel documents before you can proceed any further. Have them in your hand, ready for inspection.
• The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
• Electronic devices like phones and laptops will also need to go on a tray to be scanned. No need to worry though, you'll be back online before you know it.
• Travelling with your favourite perfume or cologne? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's OK to bring with you in your carry-on baggage.
• Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and other heavy shoes are usually subjected to extra screening.
• Airlines will not allow any sharp items or pocket knives in your carry-on baggage. If you must bring these kinds of items, pack them in your checked luggage.
