AA's ORD-ZRH-ORD route back then carried the same flight numbers as the DFW-ZRH-DFW route that replaced it in 2000: AA38/37.
The November, 1998 schedules on the route indicate:
AA38 ORD 1630 ZRH 0810+ 762
AA37 ZRH 1005 ORD 1310 762
(The flight number, though not the aircraft, originated in LAX back then, and while the flight is indicated in this timetable as operating with a 767-200 for the winter months, I know the flight did often get 767-300ERs in the summers.)
