I was fortunate enough to be able to fly DL FC three times in the 90's. As Pioneer notes it was not easy to get up there...you had to be a Royal Mediallion (the top tier of the day) to be able to claim a FC award ticket. I burned about 200,000 miles for my honeymoon in 1993 and scored two FC tix RT DFW-PDX-BKK (with stops in SEL and TPE).

IIRC the MD-11 cabins were laid out in three rows of 2-2-2. Back then you could smoke and Row 3 was smoking. Seats were comfy enough but nowhere near the comfort of today's flat bed seats. Perhaps 150 degree recline, seat width of 22-24 inches, adjustable headrests and legrests. Large center console between seats in each pair, removable

As noted by Pioneer, very attentive service. Mrs. DL and I were the only pax from SEL to BKK with two FAs and the Purser to look after our needs. Caviar, vodka, canapes/appetizers, soup, salad, entrees, cheese, dessert, all washed down by a very nice Taittinger Comtes de Champagne 1985 (we left the aircraft in BKK with three full bottles).

Return trip was equally nice although I had to deal with the unpleasant transpac reality of two Monday mornings in a day.

A few years later, as they were rolling out BE, I got a courtesy upgrade to FC on an L1011. The caviar was gone by then...I'm pretty sure that the only thing that was still FC was the seat. Pretty much the same layout and seat setup as the MD-11, but the equipment was ~10 years older and showed its age.

It's interesting that although the equipment (seats, AVOD, safety, fuel efficiency) has gotten so much better since then, the service has gotten so much worse. FC FAs in the old days were proud of what they had accomplished to make it where they were, and it showed in the level of customer service one received. Nowadays most airline staff (moreso onother airlines than on DL) are "survivors" who view the customer as an incovenience.
