We've rounded up all the info you need to make your journey as enjoyable as possible. Follow our tips and you'll be speeding through airport security and enjoying San Antonio in no time at all. What to pack in your hand luggage:

• The trick to having a stress-free travel experience is to pack ahead. So, let's start with the basics: passport, boarding pass, bank cards and important medications. Next, take on board items that'll help while away those hours, like some electronic gadgets or a magazine. It's also a wise idea to pack your chargers, a quality neck pillow and a pair of headphones. Last but not least, be sure to pop in toiletry items like a toothbrush, lip balm and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• While the list of prohibited items differs between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, fuel and fireworks. Sporting equipment like ice skates, and items that could harm passengers, such as firearms and ammunition, can't come on board with you either.

What to wear on a flight:

• You'll want to go for comfort over style. Prepare for changes in temperature by dressing in layers, and pick easy-to-remove shoes like sneakers.
• Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Lower your risks by drinking water, keeping your ankles and legs moving and wearing compression socks to help improve your circulation.

As seasoned travellers know, the secret is to be well organised before you get to security. That way, you'll be hopping onto that plane to San Antonio before you know it. Follow these helpful tips and get your trip off to a terrific start:

• Keep your travel documents and ID close by. They'll be the first things you'll be asked to show at airport security.
• Next up, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Personal belongings like your belt, jacket and headphones will be required to go through the machine.
• All electronic devices, including your phone and laptop, are also required to be separately scanned.
• Can't travel without your favourite cologne? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can keep it with you on board.
• There's a chance you'll need to remove your shoes for scanning, so wearing slip-on sneakers is always a good idea.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed in the cabin.
