The National Air Transportation Association has entered into an agreement with HD Supply Facilities Maintenance to provide association members with discounted supplies such as knee protection, ramp cones and eyewash stations as well as other commercial products. A spokesman for the NATA said it represents a saving of up to 14 percent off HD Supply’s core catalog prices. “We have provided HD Supply a list of our member companies and we will work with them to make sure they maintain a current list as new members join the organization,” he told AIN.
