Cheap Flights to San Antonio from HK$664

We've rounded up all the info you need to make your journey a stress-free experience. Follow our tips and you'll be breezing through the airport and seeing the best of San Antonio before you know it. What to pack in your hand luggage:

• The trick to having a worry-free flight experience is to plan ahead. Start with the essentials: passport, official ID, credit cards and vital medications. Next, bring items that'll help while away those hours, like your laptop or a good book. You'll also want to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Finally, don't forget to chuck in toiletry items like a toothbrush, cleansing wipes and a spare change of clothes.

Do not pack the following items in your hand luggage:

• While the list of restricted items differs between air carriers, the general rule to follow is nothing flammable, sharp or explosive. This includes things like screwdrivers, pocket knives, spray paint and fireworks. Sports equipment like golf clubs, and objects that could harm passengers, such as pepper spray and guns, won't be allowed on board either.

What to wear on a flight:

• Comfort should be your main concern when choosing what to wear on board. Loose clothing is a sensible option, as are flat, slightly roomy shoes.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To minimize your risk on board, drink plenty of water, consider wearing compression socks and keep your legs and feet moving.

The answer is simple — be prepared. We've compiled some handy tips and tricks for a stress-free trip through airport security. Look out San Antonio, here you come:

• First things first. Your travel documents and passport will need to be presented to airport security personnel. Keep them within easy reach so you don't hold up the queue.
• Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Items like your jacket, belt and earphones need to go through the machine.
• All your electronic devices, including your laptop and phone, will also need to be separately scanned.
• Any gels or liquids, such as perfume or hairspray, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
• The right choice of footwear can save you several minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
• Airlines won't allow any sharp items or pocket knives in your hand luggage. If you must bring these kinds of items, pack them safely in your checked baggage.
