Cheap Flights to San Antonio from HK$5,069

Depending on where you're coming from, your journey to San Antonio could be no sweat at all or it could go on forever. We've put together some useful travel tips that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

• The secret to having a great flight experience is to pack in advance. First up, the essentials: passport, travel docs, credit cards and daily medications. Next, take on board items that'll help keep you entertained, like some electronic gadgets or a juicy novel. It's also a wise idea to pack your chargers, a quality neck pillow and a pair of earphones. Finally, don't forget to chuck in toiletries like a toothbrush, facial wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your pocket knife, and products which are flammable or explosive, such as aerosol cans, flares and strong acids, are also prohibited.

What to wear on a flight:

• The aisles of an aircraft aren't the place for a fashion parade. Dress in comfortable layers and pick shoes that are flat, roomy and easy to pull on and off.
• Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

Being organised before your flight can make your trip to San Antonio easy and painless. Check out our useful tips and tricks for a stress-free journey through security:

• First things first. Your boarding pass and travel ID will need to be presented to airport security personnel. Have them easily accessible so you don't have to dig around for them.
• Time to strip down. Well sort of. Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
• All your electronic devices, including your phone and laptop, will also need to be separately scanned.
• Any liquids or gels, such as hair oil or hand cream, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
• Slip-on shoes are a clever footwear choice as you're less likely to be asked to remove them when going through security. Boots and other heavy shoes are often subjected to extra screening.
• Airlines will not allow any sharp objects in your carry-on baggage. If you must bring these kinds of items, pack them in your checked luggage.
