Do you have any tips for my flight to San Antonio?
If you're poorly prepared, travelling can be tough. But there's no need to hit the panic button just yet. Follow these handy hints and enjoy a trouble-free start to your getaway in San Antonio. What to pack in your hand luggage:

  • First and foremost, pack your passport, important documents, credit cards and medications. Next, you'll want some in-flight entertainment to while away the time. A juicy book and a tablet crammed with your favourite movies are some great options. If you intend to catch up on some sleep, a comfy neck pillow and some earplugs will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you step off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a knife or scissors) lurking in one of the compartments of your carry-on luggage. Other banned items include flammable or explosive substances, like aerosols and matches, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear during your flight. Loose clothing is a sensible option, as are flat, enclosed shoes.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long flights. Lower your risks by drinking water, keeping your legs and feet moving and wearing compression socks or tights.

How to get through airport security fast when flying to San Antonio?
The trick is to be well organised before you get to airport security. That way, you'll be boarding that plane to San Antonio in the blink of an eye. Follow these helpful tips and get your trip off to a great start:

  • Security personnel first need to know that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them ready for inspection.
  • Your jacket, belt, keys and other contents of your pockets, like your headphones, will be required to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • All your electronic gadgets, including your laptop and phone, are also required to be scanned separately.
  • Remove all liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • There's a good chance you'll be required to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a clever idea.
  • Airlines will not allow any sharp or pointed objects in the cabin. If you need to bring these kinds of items, pack them in your checked luggage.
