Cheap Flights to San Mateo from HK$1,734

If you're poorly prepared, travelling can be challenging. But there's no need to worry. Follow these helpful hints and enjoy a hassle-free start to your getaway in San Mateo. What to pack in your hand luggage:

• Air travel can be a pleasure if you pack the right gear. Firstly, you'll want a few basic toiletry items, such as deodorant and a toothbrush, a spare change of clothes and a few magazines. Next, find a spot in your bag for your electronic gadgets, chargers, your important medications and maybe a cosy neck pillow as well. Lastly, remember to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

• Double-check that you don't have sharp objects (like a knife or scissors) hiding in the bottom of your carry-on luggage. Other restricted items include flammable or explosive products, like aerosols and matches, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Go for comfort over style. Prepare for changes in temperature by dressing in layers, and wear flat, slightly roomy shoes like sneakers.
• Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clotting due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

The secret is to be prepared before you get to the airport security gate. That way, you'll be stepping onto that plane to San Mateo in no time flat. Follow these helpful tips and get your holiday off to a terrific start:

• Airport security personnel first need to see that you have a valid ID and travel documents before anything else. Keep them within easy reach.
• After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Personal belongings such as your jacket, belt and headphones need to go through the machine.
• Your electronic devices like phones and laptops will also have to go on a tray for inspection. Don't worry though, you'll be back online soon enough.
• Travelling with your favourite cologne or perfume? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on baggage.
• Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when going through security. Safety boots and other heavy shoes are usually subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board.
