No need for any file number. When your friend goes into the office, He'll either see Capt. Kraby or Capt. Mills. They'll be able to pull your file right in front of his computer. Be sure your airlineapps are filled out correctly!!! You may also have your friend bring in a copy of your resume if you like.

The whole application process at DL is all electronic, they just need to pull your name and voila!
