Cheap Flights to San Antonio from HK$839

We've pulled together all the info you need to make your journey a stress-free experience. Follow our tips and tricks and you'll be cruising through airport security and having a ball in San Antonio in no time. What to pack in your hand luggage:

• It's easy — first, pack your passport, travel docs, bank cards and medications. Next, you'll need some entertainment to help pass the time. A juicy novel and a laptop filled with your favourite shows are some terrific options. If you intend to take a quick nap, a neck pillow and a pair of earplugs will also be useful. Finally, leave space for a toothbrush and some deodorant to ensure you step off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have sharp objects (like a pocket knife) hiding in the bottom of your hand luggage. Other prohibited items include explosive or flammable goods, such as aerosol cans and bleach, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Comfort should be your main priority when choosing what to wear on board. Loose clothing is a sensible choice, as are flat, slightly roomy shoes.
• The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. Reduce the risks by drinking water, keeping your ankles and legs moving and wearing compression socks to help improve your circulation.

The trick is to be organised before you reach the airport security gate. That way, you'll be stepping onto that plane to San Antonio in no time at all. Follow these tips and get your holiday off to a fantastic start:

• Security personnel first need to know that you have a valid ID and matching travel documents before you can proceed any further. Keep them within easy reach.
• Next up, both you and your carry-on luggage must be X-rayed. To speed things up, take off anything that might set the alarms off. Personal belongings such as your belt, coat and earphones need to go through the machine.
• For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronic devices will also need to go through the scanner.
• Any liquids or gels, such as toothpaste or perfume, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
• Slip-on shoes are a sensible footwear choice as you're less likely to be asked to remove them when passing through security. Boots and heavier-style shoes are usually subjected to additional screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed on board and will be confiscated.
