Why do people stop using the airmail?

Airmail was one of the first communication media around the world, by the air mail is sent separate letters or packages that are received by family and friends. But what is the main reason I stopped using it in this way?
According to what I have researched online, and found that in some countries such as Greece still use it but not so often by the danger to the information. In the second world war, airmail was by pigeons and airplanes different information and messages sent to know the position of the enemy or to send food or reinforcements.
Today to send any message it does so through text messaging via a cell phone, or e-mail aside comunicaicon this medium was very useful.
In my personal opinion this means of communication that should disappear as it is sometimes necessary to send very personal things that can not be expressed only in words or drawings on a computer.
