My last UA DC-10 flight was in early 1990 SEA-ORD on the way to LHR on BA (back when UA and BA were an alliance). I remember the aircraft being packed.
My most memorable DC-10 flight on UA was SEA-HKG back in 1983. The aircraft, a Series 30, was leased from CP Air (the walls had canadian images all over the place-maple leaves, beavers, etc. along with standard UA seats), and the flight was 12 1/2 hours. They called it Royal Pacific Service back then and was very nice. The food was good, and the service very helpful and attentive. I couldn't wait to arrive though the flight was so long and boring... Ah, those were the days!
