Re: DL retiring MD-80s quickly

There will be a mass retirement at the end of 2020. I think the fleet will trickle down at a rate of 3-5 per month to under 20 airframes by Nov 2020 and all are retired at the end of Dec. The trickle down rate coincides with the HMV or C check Due dates for the remaining aircraft.
