For those asking if Delta can see if you have family members at Delta or not the answer is yes they could but they choose not to. I emailed airline apps because they have a section where you can list family members who work in the airline industry. They replied telling me that Delta chooses NOT to see that. That is why when you print out your application you don't see it. However, if they write you a LOR then the board will see it when and if you get an interview.
