1. No “prohibited items” to the airport (elements of common sense, like Swiss Army knives, lighters, etc)
2. Use hand luggage for valuables such as cash, a laptop computer and jewelry. Also be placed in hand luggage, cameras and undeveloped film (The X-ray film does not damage the speed under 800).
3. Put your business card or personal contact at the bottom of the laptop and other valuables you deem necessary.
4. Avoid using metal / aluminum foil along with clothing, accessories and objects (like coins, money clips, cell phone, keys, medication, gum, batteries, lottery tickets, cigarettes, etc). In the case of things like coins and keys, try to bring in a bag full making it easier for them and put them again later.
5. Avoid wearing shoes that contain metal and / or have thick soles. The reason is because the shoes do not stumble on alert to their own specific search procedures applied (so that nothing can be hidden in shoes).
6. Indeed, the holidays are approaching, but be sure to pack the gifts on arrival or ship rather than take them to the airport pre-packaged, as these will be reviewed by security personnel.
7. Arrive an hour to an hour and a half before the scheduled departure time, because you are looking for does not matter if your plane leaves in 5 minutes or 5 hours.
In light of recent world events, the increased security at the airport (and beyond) the measures are a fact of life, with no signs of slowing in the short term. However, after all  a simple system can help avoid the crowds  along the turbulent journey we call life.
