7 things you don't even think happen on airplanes and airports

Air travelers do not always know everything that is happening around them. There are many things that are not revealed but that may cause concern. Understand what happens when you board or are on a plane and gain insight into your travels.

1 - Zippers can be opened easily

There are people who lock their bags so that they are not opened, so that their belongings are safe, but this is useless. Unzipping the case is quite simple, and just use a simple pen. The bag is opened, checked, and then zipped again, as if nothing had happened, and this procedure can also be used to check suspicious or unidentified bags.

Be careful here, because this trick can be known to bad guys and malicious people who can steal something - both material and sentimental - from your bag if it gets lost, and the damage is yours. To avoid this type of problem, choose to use luggage with a fixed locking system or security codes and take out travel insurance that provides coverage for this type of eventuality.

2 - Air toilets may not be very hygienic

Hand washing after going to the toilet is indispensable, but on airplanes this may not be as efficient as you might think. Even though water tanks are cleaned periodically, parasites create resistance to disinfectants. Not to mention that the potable water and wastewater ports can be close together and handled at the same time, which can lead to contamination. Ew ...

3 - Bathroom doors can be unlocked outside

Airplanes have devices that allow the bathroom doors to be opened from outside in case of any eventuality during the flight. Of course this is not to spy on who is inside it, but in case someone gets stuck!

4 - Is there a time limit for oxygen masks?

Do you know those masks that are released in case of cabin depressurization? They provide only 15 minutes of oxygen for passengers, as this is the time considered necessary for the pilot to be able to reduce the altitude of the aircraft and everyone can breathe normally without using them.

5 - Pilot and co-pilot eat different foods

The meals that are served to the pilot and co-pilot will never be the same. The explanation for this is quite simple: if one of them gets sick with food, the other will still be able to fly the aircraft.

6 - Beware of the headphones

If you think the headphones available on flights are new, you are making a mistake. As much as they are packed, it is quite likely that they have already been previously used, sanitized and repackaged. The same goes for blankets and pillows available on airplanes.

7 - Lights are off for a reason

When the lights on the plane go out, many people believe it is so that passengers can get better rest. But the truth is that this is a safety procedure if an evacuation is required. Flight attendants will be alert if the aircraft needs to be evacuated, and the eyes will be better adapted to the darkness of the night, assisting outside.
