When scheduled flight times are different, it is for two reasons: 1) padded times added by the airline to improve their reported on-time performance, or 2) prevailing windws.
Number 2 is most common for east-west flights, but since the D.F. and Chicago are nearly north and south from each other, it's probably mostly that the time of the flights means the airline pads it differently. Prevailing winds may also play a role, however, since the jet stream does have a northwesterly flow across most fo the eastern half of North America.
