Depends on your definition of long-haul, but the timing of the drawdown was a year earlier.
Back in Winter 1991, UA only had 10 flights at MIA. 1x to DEN/MIA, 3x to IAD, and 5x to ORD.
In Winter 1995, UA had picked up some of the LatAm routes, but a lot of that was close-in flying (e.g. PTY, CCS). True long haul was limited to FRA CNF SCL LIM GIG EZE GRU.
All of the short haul international except for CCS was pretty much gone by 2000, but GRU EZE SCL LIM GIG still existed into 2002.
By summer 2003, all that was left were EZE and GRU.
