The DL social media team seems to do a great job and has fun with showcasing company history.

DL just ended an 80s flashback week on their Facebook page, including lots of pictures of everything DL from the 1980s.
My post is mainly for the DL corp team members who read these threads:
Please suggest that a few planes in the domestic fleet be painted in heritage livery. Maybe an MD-90 or two (or even a domestic 767 if one will be hanging around for a while) with the late 80s DL livery and a newer A320 or two with the mid-2000s NW livery or the infamous "Bowling Shoe" livery.
