I agree it's "Wrong", but I asked the ATL Int. CPO, "Who do I write a letter of recomendation to..." and the answer they gave me was exactly what Elvis said; The applicant has to do his app. on Airline Applications and in the app, he includes your Delta.com email address (I had to activate mine, I never use it, and I had to change all my gd passwords just to do it!)

Then, when your friend finishes, you will get a request type email on your Delta.com address, and you clik the link, write the letter directly on the Airlineapps.come site.

Huge pain the ass, if you've never activated your Delta.com email, especially when we aren't even hiring...

You would think an Employee could find SOMEONE in Delta Personel to write to, but the app stack is so big, they won't even look at one, unless it comes through Airlineapps.com first.
