Really, you really want to go into this.

For decades airlines would not interview a woman or person of color.

Let's take present day Alaska for example, the only way to get an interview is to have a silver bullet from a current employee. If those current employees got their jobs during the times of hiring only white male pilots, that skews the number of new interviewees in favor of white male pilots.

Other airlines, AA friends and family hiring in their previous hiring cycle, same philosophy. Old white captain's sons and grandsons.

In my last CQT (recurrent) the captain, who had a flip phone, could not stop bragging about how he got his son hired.

That's your perpetual white hetero convention at work.

I fly for US Airways/AA, who exactly do you fly for Herman?
