Human Factors; Procedure
XA:00 is cut off for check in on XA:30 flight. After verifying all bags had been sent plane side I went plane side to help finish up; i.e.; bring down gate check bags/strollers; pull belts; close doors etc. At about XA:15 after being told by Gate and Lead Ramp that we were clear on ALL bags I proceeded back in to bag room with lead to finish close out. After closing out flight and finalizing flight for departure Lead Ramp realized a mistake in the loading occurred with the loading of dry ice quick packs in the forward compartment. Efforts were made by Operations to call flight back to gate; but to no avail. Aircraft departed gate XA:22 and was airborne at XA:32.
Quickpacks with limited quantities of Dry Ice staged and loaded in forward compartment of A320; contacted load plan and attempted to contact aircraft but was unsuccessful. Aircraft flew to ZZZ1.
Ramp personnel reported aircraft departed with dry ice packs erroneously loaded in forward compartment.
