I don't believe DL
is looking for any 732 replacemen anytime soon. Ages ago I posted a thread asking this same question. DL
within the last year has recruited many 732's out of storage and has converted all from Delta Express back to the mainline. They appear quite comfortable with them now. Also, keep in mind that the DL
732's were built in the early 1980s, much later than the majority of the 732's. And thus, they are some of the newest. If Delta has brought them out of storage recently, I don't think they will return to that state permanently for some time.
