Flew down to Atlanta yesterday on a Pilots n Paws mission. KLZU - Gwinnett County was very helpful in our transport. For a pilot, they waived the $25 landing fee, and also offered us a 50 cent fuel discount. Their prices were very high for fuel though ($1.65 more than our home base), so we declined on fuel.
They allowed the dog in the lobby while waiting for us to arrive and really took care of her!!
