Human Factors
Captain called to advise that because there are both live animal and dry ice on board they must run air conditioning pack which is a 1.1 % drag/overburn. He advised same issue happened out of ZZZ and delay incurred on both flights. I advised him I would report this issue; since there is no alert generated from weight/balance system to flight planning like there would be in dry [ice] supplemental procedures and/or carp messages. This scenario will continue to occur. I advised him I have to recalculate flight plan with 1.1 % over burn and changed payload since it is lighter than original plan. Sent mini flight plan. The cause is no alert program within weight/balance system to notify dispatcher in advance. I suggested to have the it people with weight/balance and flight planning create a fix (similar to dry ice supplemental procedures and captain report).
Air Carrier Dispatcher reported Captain requested additional fuel and updated Weight & Balance data due to dry ice and live animal in cargo compartment. Dry Ice and live animal in cargo requires the operation of cargo AC Pack during flight.
