I used to love those 727s. I first flew on one in 1964, on American. It was absolutely brand new, and was gorgeous. I flew many times on the 727 on United also.
I enjoyed many trips on the 727-200. I think the extra length makes it more graceful and attractive. The 727-200 cost about 2,500 an hour to run, compared to 2000 for an MD-80. This is mainly due to the higher fuel consumption a three engine aircraft requires. The 200 was last produced in 1984. It also gave very hard landings, as I recall. It's time has passed, but it was a great aircraft. I flew many 727-200s on Delta, and enjoyed my flights tremendously. I last flew on a 727-200 (on Delta)I also flew on many on Alaska Airlines in the 1980s. The legroom was fantastic, as was the service. When I would fly them into SJC, I really enjoyed seeing the automatic stairs come out, and extend, so we could deplane. I also flew many 727s on Western...those were nice too, and their aircraft again had lots of legroom.
