Narrative:

The dfw area had been impacted by a line of thunderstorms all evening. Throughout the evening; tmu was responsible for initiating swap's and reroutes for the thunderstorms. There were over 70 diversions due to the airport closing; volume and other weather issues. Airline companies would call the traffic management unit and ask us to remove the flight plan on several flight plans so that they could re-file. The tmc working the NC1 position got a request to remove a flight plan and he asked me to remove it since my position is in front of the kvdt computer. The wrong flight plan was removed and the track disappeared from the mdm working air carrier X. The more times you have to communicate an instruction; the more chances there are of miscommunication; especially when complexity and volume are involved. If the airline's dispatch could remove the flight plan themselves; then that would cut out that chance of miscommunication.
