We've pulled together all the info you need to make your flight as enjoyable as possible. Follow our tips and you'll be speeding through airport security and exploring San Antonio in no time flat. What to pack in your hand luggage:

• The trick to having a hassle-free travel experience is to be prepared. Start with the essentials: passport, boarding pass, bank cards and daily medications. Next, take on board items that'll help keep you occupied, like some electronic gadgets or a thrilling book. It's also smart to pack your chargers, a neck pillow and a pair of headphones. Last but not least, don't forget to chuck in toiletries like a toothbrush, lip balm and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your trusty pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, flares and poisons, are also prohibited.

What to wear on a flight:

• Your aim here is to feel as comfortable as you can. Opt for shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and remember to bring a jacket in case you get chilly in the cabin.
• Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.

It's all about being prepared. We've compiled some handy tips and tricks for a stress-free trip through airport security. Watch out San Antonio, here you come:

• First things first. Your travel ID and boarding pass will need to be inspected by airport security. Keep them handy so you don't have to dig around for them.
• Next up is the X-ray machine. Remove anything metal on you that is likely to beep. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
• For just a few moments, you'll have to unplug from the digital world. Your phone, tablet and any other electronic gadgets must also go through the scanner.
• Any gels or liquids, such as toothpaste or perfume, that you want to take on board must be 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 practical footwear choice as you're less likely to have to remove them when going through security. Big boots and other bulky shoes are often subjected to additional screening.
• Airlines will not allow any sharp objects in the cabin. If you need to bring these kinds of items, put them in your checked baggage.
