I still remember a cold dinner I was served on DL from ORF-ATL in roughly 1988...in coach...it was a casserole dish with a scoop of potato, a scoop of tuna and a scoop of egg salad served with a couple packages of sesame crackers and a chocolate candy. Likewise, a snack on YX (Midwest Express) same time frame at about 5 in the afternoon between DTW and MKE was apple chips served with a cinnamon cream cheese dip...impressive and perfect for the flight time.
