Narrative:
Captain called the dispatcher to discuss routing las to bos. Captain and dispatcher agreed on a different route to fly. Dispatcher issued new flight plan with new routing, but did not file new route with ATC. Flight departed lax and in ZOA ATC area started flying the second route which was discussed with dispatcher. ATC controller was expecting first route. Center controller notified dispatcher and captain notified dispatcher and misunderstanding was cleared up with all parties involved. The initial routing was a routing requested by ATC for the lax-bos city pair to be flown. This route was being affected by WX so that is the reason for the route change. Dispatcher's workload was high due to dispatching transcontinental flts. ATC was issuing playbook routings along with playbook routings with amendments which the dispatcher had to verify each routing for each flight with the routing requested by ATC to file. This second routing for this lax-bos flight was not refiled and the initial flight plan was not canceled. The pilot did not notice the difference between the clearance and the flight plan issued to him.
