The Federal Aviation Administration has opened an investigation into whether airports in San Antonio, Texas, and Buffalo, New York, discriminated against Chick-fil-A when they denied the fast-food chain vending space, the U.S. Transportation Department said Friday.

“The Department has received complaints alleging discrimination by two airport operators against a private company due to the expression of the owner’s religious beliefs,” the federal said in a statement. “FAA’s Office of Civil Rights has notified the San Antonio International Airport (SAT) and Buffalo Niagara International Airport (BUF) that it has opened investigations into these complaints.

"The FAA notes that Federal requirements prohibit airport operators from excluding persons on the basis of religious creed from participating in airport activities that receive or benefit from FAA grant funding," the statement continued. "The findings of the investigations will be communicated to the complainants once the investigations are completed.”
