DC-10 confession time from over here as well; there were quite a few over the years. First was a Laker DC-10-10 Manchester to Toronto and back in 1974, ostensibly a charter but by then they were just selling seats through travel agencies. Laker always tried to be a bit different, they didn't have a "captain", they had a "commander". Then several flights on the unusual British Airways operation from London to LAX in the late 1970s. BA used an Air New Zealand aircraft for this, and although the aircraft continued overnight on to Honolulu and Auckland as an Air NZ flight the London leg was a wholly BA badged and staffed operation, they trained up a group of pilots on the aircraft for it. I recall that in December Air NZ had put Christmas decorations across the cabin hung from the ceiling, never seen that before or since; in turbulence they all swayed around.
British Caledonian Charter, a separate company to the main B.Cal, took us from Gatwick to Faro in Portugal one summer week, and then I can count more sectors than I first thought with AA in the US; LAX to ORD, DFW to LAX, and LAX to JFK. None of these really runs to a widebody at all nowadays. I think that left-hand spiralling and seemingly hand-flown descent overhead JFK down onto 22L, nicely viewed from a left-hand window seat, was my last one - obviously quite a few years ago.
Only one still around seems to be the B Cal Charter one from that fun holiday in Portugal 30 years ago (it was the same aircraft out and home - they only had two), with FedEx now as N40061. If you see it around a US ramp one day, give it a wave from me.
