Hey guys, I just wanted to give you a heads-up. I received a response from Delta.
From the e-mail:
Regretfully, this information is not available to the public. As such,
I am unable to fulfill your request for a contact person. Additionally,
this information is confidential to Delta Air Lines and not released to
the general public.
So it seems there is no way to get a hold of that person in question being just 'general public'.
I do respect their policy.
