Delta Air Lines (Atlanta) recently passed a quiet milestone with one aircraft type. The carrier has now operated the venerable Boeing 757-200 type for over 30 years. The first Boeing 757-200 (757-232 N602DL, msn 22809) was delivered on November 5, 1984 and placed into revenue service on December 1, 1984 along with N603DL. The initial routes were from Atlanta to Birmingham, Dayton and Jacksonville.
