Cheap Flights to San Antonio from HK$569

If you're poorly prepared, airports and flying can be a real challenge. But there's no need to hit the panic button just yet. Follow these tips and tricks for a stress-free start to your time in San Antonio. What to pack in your hand luggage:

• First and foremost, pack in your passport, travel docs, bank cards and medications. Next, you'll need some in-flight entertainment to while away the hours. A thrilling book and a phone crammed with your favourite movies are some great options. If you plan to take a short nap, a quality neck pillow and a pair of earplugs will also come in handy. Finally, find room for a toothbrush and some facial wipes so you'll step off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a pocket knife lurking in one of the zippers of your carry-on luggage. Other restricted items include explosive or flammable substances, such as fuel and matches, 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 aircraft are no place for a fashion parade. Layer up with comfortable clothing and choose shoes that are flat, enclosed and easy to pull on and off.
• Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-distance flights. Reduce the risks by drinking water, keeping your feet and legs moving and wearing compression socks to help your circulation.

Being prepared before you get to the airport will make your getaway to San Antonio quick and painless. Read through our handy hints for a speedy journey past security:

• Security personnel first need to check that you have a valid ID and travel documents before you're allowed to proceed any further. Keep them within easy reach.
• Next up is the X-ray machine. Remove anything metal on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• All your electronic devices, including your laptop and phone, must also be scanned.
• Any liquids or gels, such as perfume or toothpaste, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and other heavy shoes are usually subjected to extra screening.
• Airlines will not allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, pack them safely in your checked baggage.
