8 JetBlue’s brand is superior to Frontier’s because of its enhanced customer service, fair compensation for its Crewmembers, and differentiated business model “JetBlue Effect” has the strongest impact on legacy fares of any other airline on the nonstop routes it flies Customers should not have to choose between price and quality service . JetBlue’s customer service has won the company hundreds of awards since its inception – including the “Travelers’ Choice Award” multiple times Air Line Pilots Association reported that Frontier pilots were the lowest - paid narrow body pilots in America – often 40% 1 under peers; in contrast, JetBlue offers Crewmember compensation in - line with industry standards and provides top notch benefits Women and people of color comprise 46% and 59% of JetBlue Crewmembers, respectively, and the combined airline will carry this ethos forward on a much larger scale 8 1 Air Line Pilots Association, "Profits over Pilots at Frontier Airlines .” JetBlue is a Better Home for Spirit’s Customers, Team Members, and for the Community at Large
