Cheap Flights to Houston from HK$6,821

If you're not prepared, airports and flying can be tough. But there's no need to panic. Follow these handy tips and enjoy a trouble-free start to your holiday in Houston. What to pack in your hand luggage:

• The secret to having an awesome travel experience is to plan ahead. So, let's start with the essentials: passport, travel docs, credit cards and daily medications. Next, take on board items that'll help pass the time, like your laptop or a good read. It's also smart to bring your chargers, a quality neck pillow and a pair of earplugs. Finally, don't forget to chuck in toiletry items like a toothbrush, deodorant and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a pocket knife hiding in one of the compartments of your carry-on luggage. Other banned items include flammable or explosive products, such as bleach and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• The aisles of an airplane are no place for a fashion parade. Dress in comfortable layers and choose shoes that are flat, roomy and easy to slip on and off.
• Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-distance flights. Reduce the risks by drinking water, keeping your legs and feet moving and wearing compression socks to help your circulation.

It's all about being prepared. We've compiled some tips and tricks for a fuss-free trip through security. Watch out Houston, here you come:

• Your boarding pass and travel ID will need to be shown to airport security personnel. Keep them handy 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 things like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• Electronic devices like laptops and phones 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.
• Don't forget to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
• It's also likely that you'll be asked to take your shoes off for scanning, so wearing slip-on shoes is always a good idea.
• Knives and other sharp items are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked suitcase.
