Boeing B757, with more 1000 built since 1982, could have its production ceased as early as summer 2004, unless there are new customers for the aging jet.
Meanwhile, Boeing is also looking for a launch customer for the 737-900X, a derivative that would have 200 to 220 seats, similar to Boeing 757 of 200 seats.
