It may be too late for your project, but you should be able to find an annual report from 2000 and then again from 2001. It always listed the number in the fleet, the number owned, leased, and on order. Also, if you still know somebody with a Unimatic sign-on they can look it up but I would have to think of the entry to type in to get what the current status of the plane number was. I will try to dig up my notes from load planning and see if the notes are in there. I want to say it was something like, CURRTG/#### with the #### being the four digit plane number that was on the nose of the aircraft. I'm sure by now they are all out of the system.
On page 34 of the 2000 annual report it stated.....

More than enough to replace the 727-200 fleet. However, most were the A319-100 with a seating of 120 to replace 141 so I don't know if it would have gained in total seats available. However, I'm sure the fuel savings would have offset the difference in the seats available.
IIRC United donated some of the 737-200's to various flying schools and saw that the 727-200's were sent out of the US so they would not have to compete with the planes. I don't know how far back Newsreal is kept, but again if you know somebody have them search around the end of October 2001 if Newsreal is still available. I think that it was only retained for a year or two, but I could be wrong.
Anyway, thanks for the stoll down memory lane when UAL was on top!
