Not long after arriving, the Headmistress gave the announcement of how they were to get to Gringotts and what to do upon their arrival. Not only would she be on her best behavior, there was little chance of her wandering off.

Just before she headed towards the fireplace, her heart pounded with a brief moment of panic, then she realized that had to be easier than port key. It just had to. After taking a deep, calming breath she stepped up, grabbed a handful of floo powder, tossed it in and said "Gringotts!" Then she was gone.
