Zephyr Airlines, a new air carrier headquartered in Atlanta with routes from London to Tokyo,studied the psychology of passengers and determined that more than 90 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 40 percent of the flight attendants hired were black. What violations of federal law has Zephyr committed, if any? can you give a lots of explanation, thank you.
