Cheap Flights to San Antonio from HK$1,600

No matter where you're coming from, flying can be a pleasant experience if you've planned ahead. We've compiled a list of essential travel tips that will get your San Antonio holiday started on the right note. What to pack in your hand luggage:

• Travelling on a plane can be a cruisy experience if you take the right stuff. First of all you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh change of clothes and a few magazines. Next, find room in your carry-on bag for your phone, tablet and chargers, any vital medications and maybe a neck pillow too. Last, but definitely not least, be sure to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

• While the list of restricted items differs between air carriers, the general rule of thumb is nothing sharp, flammable or explosive. This includes things like box cutters, razor blades, spray paint and flares. Sports equipment like ski poles, and items that could harm other people, such as pepper spray and firearms, can't come on board with you either.

What to wear on a flight:

• Your aim is to be as comfortable as you can. Opt for a pair of slip-on shoes, dress in loose, breathable clothing and don't forget to bring a pullover in case you get chilly in the cabin.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to improve your circulation.

Being prepared before you get to the airport will make your getaway to San Antonio a breeze. We've rounded up some top tips for a speedy journey past security:

• Security personnel first need to make sure that you have a valid passport and matching boarding pass before anything else. Have them ready for inspection.
• The X-ray machine is up next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
• For just a few minutes, you'll need to unplug from the digital world. Your phone, laptop and any other electronic gadgets will also need to go through the scanner.
• Can't travel without your favourite hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's OK to bring with you in your carry-on luggage.
• The right choice of footwear can save you valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
• Knives and other sharp items are not allowed in the cabin. They'll be seized at security, so put them in your checked suitcase.
