Rainbow Airlines, a new air carrier headquartered in Chicago with routes from Rome to Canberra, extensively studied the psychology of passengers and determined that more than 93 percent of its passengers felt most comfortable with female flight attendants between the ages of twenty-one and thirty-four. To increase its profitability, the company issued a policy of hiring only such people for jobs in the air but opened all ground jobs to anyone who could otherwise qualify. The policy made no racial distinction, and, in fact, nearly 30 percent of the flight attendants hired were black. What violations of federal law has Rainbow committed, if any?
