Re: Delta Introduced First Of 33 Recently Purchased Used Boeing 737s

Delta has bought a lot of airplanes over the years from other operators. Before the ones mentioned there were also Ex Eastern 727 and L-1011 in the fleet. I also recall there were a few 767 and 737 Classics that were second operator airframes.
