On my first trip to Hawaii in 1987, I saw some MD-80s, but I flew on a Hawaiian DC-9-14, N930EA. It was not ex-Eastern, even with that tail number. I remember that it still had open overhead racks. All the rest of my Hawaiian inter-island flights were on DC-9-51s, and one of them was ex-Eastern, N420EA. This December I get to fly on two of their 717s. I'm looking forward to it, but I'll miss their DC-9s.
