It used to be my favorite airline, but the last few times I flew Delta, I noticed it wasn't what it used to be. Some of the 727s have worn seats, and I had to brush the crumbs off mine before I sat down. I had a 767-300 from JFK to ATL, and they showed short subjects. What's so unusual about that? Well, they didn't pass out headsets, and they didn't open up the screen. It just showed on the front cabin bulkhead. I didn't complain because I didn't care to watch it anyway. I don't know whether anyone else complained or not.
The one outstanding part of Delta is the Delta Shuttle, from DCA to LGA to BOS. These 727-200s have very comfortable blue leather seats throughout in an all-coach layout with more legroom than you find in any of Delta's other aircraft. And a snack is served on every flight. I love to fly on the Shuttle.
