Procedure
ATC issued reroutes from ZDV to BDL. It was my third straight day on this desk and that reroute had been out for all 3 days.  I missed it on (flight#) resulting in a 4.4 arrival fuel. I told the crew once they entered ZMP center to request direct YYB. After Consulting with the Chief Dispatcher and ATC coordinator I advised the crew then to ask DCT NIPPY which ATC granted.  Mistakes were made on both ends. The communication with Dispatch and Crew is one of the most important safety features we have. It broke down. Once the Crew asked me for the winds at FAR YQT YYB that was when I noticed I had them filed on the standard route. At that point I got the Chief and atc coordinators involved and asked the crew to request a dct routing to NIPPY resulting in about a 5.2 landing fuel.
B737-700 Dispatcher reports not noting a NOTAMed airspace closure and files the standard route. This results in a reroute by ATC and landing with less than planned fuel.
