I had the interesting experience of flying on two of Delta's L-1011's in the last week and a half to Hawaii (trip report forthcoming).
Apparently, Delta's stockpiling the L10s on its Hawaii routes, because it uses nothing but those a/c on its several flights to Honolulu, Oahu and Kahului, Maui. At the Delta pier of the HNL terminal, I spotted three L-1011s without looking--an L-1011-1 from LAX continuing on to OGG; an L-1011-500 to DFW; and an L-1011-250 enroute to Atlanta. I was on the latter aircraft.
As a side note, our captain on the LAX-HNL segment informed us that we would be delayed momentarily on the ramp, as we were picking up a part that another L-1011 needed for repair, which was stranded in Honolulu. I later saw that aircraft in a holding area at HNL while driving by the airport, but I couldn't see the reg number.
My guess is that they're going to shift the remaining L10s to the Hawaii routes and phase them out gradually, replacing them with 764s on these routes.
The L-1011's I was on were N1731D (L-1011-1), and N741DA (L-1011-250). 1731D was a bizarre aircraft, because the First Class section was decked in wood finish and looked rather new(5-7 years old, perhaps?), while the Economy section looked like it hadn't been changed one bit since the a/c was delivered in the 70s. The decor of the cabin was in 70s-ish tones, with beige-ish/yellow walls and seats that looked like they might have seen new fabric, but definitely bore old utility buttons (ie, light switch, headphone jack, music volume/channel selector, etc.). The bins were rather worn, too.
741DA was much better--the seats looked reasonably new, in red, blue, and grey colors, although they did have a lot of loose threads hanging off them. But the aircraft seemed a lot more new and less second-hand than the previously mentioned one. The utility buttons were newer and cleaner, too, and the aircraft seemed much cleaner overall. It was also equipped with the "moving map" display, which tracked our course, location, speed, and altitude, among others, through the flight--I had no idea that DAL put this technology on an L-1011! The bins were still kind of worn, but what are you going to do, eh?
I found the L-10's seats kind of cramped and restrictive, especially compared to the 767-200 that I rode in from Cincinnati on. However, the aircraft was certainly an interesting one to fly on--I just wish Delta had a 2-4-2 configuration like the L-10 was supposed to have instead of the current 2-5-2 config. All in all, not a bad aircraft, though. Too bad it's going the way of the dodo.
