How to survive the flight to Santo Antonio?
No matter where you're coming from, flying can be a pleasant experience if you're well organized. Check out these handy tips and tricks that will help get your Santo Antonio escape started on the right foot.What to pack in your hand luggage:

  • A plane ride can be a great experience if you carry the right stuff. Firstly, you'll want some basic toiletries, such as a toothbrush and some deodorant, a clean set of clothes and a good book. Secondly, find a spot in your carry-on bag for your phone and charger, any medications and maybe a comfy neck pillow as well. Lastly, and most importantly, be sure to bring your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a sharp object lurking in the bottom of your hand luggage. Other restricted items include explosive or flammable substances, such as fuel and matches, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The main aim is to make yourself as comfortable as you can. Layer up in natural fibers and remember to bring a sweater in case it gets cool. Always go with roomy, flat shoes as it's possible that your feet and ankles will swell a little during the journey. Leave the high heels and heavy boots in your checked luggage.
  • A condition known as DVT (deep vein thrombosis) is a potential risk on long-haul flights. It results from blood clots forming due to inactivity and poor circulation. Walking around the cabin and doing regular leg and foot exercises while seated helps to prevent this developing. Wearing a high-quality pair of compression socks can also help.

How to get through airport security fast when flying to Santo Antonio?
The trick is to be organized before you reach security. That way, you'll be stepping onto that plane to Santo Antonio in no time at all. Follow these tips and get your vacation off to a flying start:

  • Airport security personnel first need to establish that you have a valid passport and matching boarding pass before anything else. Have them in your hand, ready for inspection.
  • Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn.
  • For just a few moments, you'll have to unplug from the digital world. Your tablet, phone and any other electronics also need to go through the scanner.
  • Want to bring along your favorite perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on baggage.
  • 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 wise idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked luggage. They won't be allowed on board and will be confiscated.
