Narrative:

After takeoff on runway 25 at rfd; we were cleared direct to bdf. As we turned left toward what we thought was bdf; we realized we had bfd in the FMC instead of bdf. Rfd departure told us to contact ZAU and did not say anything about our heading. As soon as I contacted ZAU I realized we were going too far east and immediately asked chicago for direct sgf which was showing more on course toward our destination. Center immediately gave us direct sgf and shortly after said rfd departure wanted to know why we turned toward the east. I told chicago we thought we were headed direct bdf and wanted to go more direct. All of this happened within a min or less after being cleared direct to bdf we just had bfd in the FMC rather than bdf. We checked and bfd was 497 mi ene from rfd and would recommend that bfd be taken out of the database so this mistake would not happen again. Callback conversation with reporter revealed the following information: the captain commented that they at first were not concerned about the direction of turn because the flight plans generated by the company's new flight planning program will often route flts in other than the most apparent direct routing in order to optimize the flight path with forecast winds.
