I work in an airline. I often see those security checks when I pick up and drop off planes. It seems that they are not short, so it is estimated that there is a requirement for height.
Of course, the most important thing to enter the airport is that you are "innocent", because you must have a pass to enter, and you must have proof of whether you have a criminal record. As long as you have not done anything bad, it is generally no problem.
It is said that the security check is not bad. Hehe, I wish you an early success.
According to my visual inspection, the increase should be at least 1.75. As for the education, I am not sure about it, so it should not be very strict. After all, it is not a technical job, and it doesn't matter much if you have a higher education. Of course, it is best to have a higher education.
