The Georgia legislature passed a tax reform bill on Thursday which excluded a provision that allowed airlines to re-fuel at Hartsfield-Jackson Atlanta International Airport without paying the state's sales tax. The exclusion was motivated by Delta Air Lines' announcement that it would join a number of businesses in ending its discount program for National Rifle Association members. The bill will cost the airline, which uses Hartsfield-Jackson as its main hub and whose headquarters are located in Atlanta, $40 million.
