Breeze Airways doesn't have a public-facing "office" in Atlanta for general customer service their main corporate offices are in Utah, but they use ground handling services, and Unifi Service handles their Atlanta operations from 950 E Paces Ferry, Suite 2000, Atlanta, GA 30326, so you'd contact them for airport-specific support, not general booking or issues. For most needs, use their website or app for booking, check-in, and customer support.
