BTN’s 2015 25 Most Influential includes executives from three airlines with contrarian models—Lufthansa, Etihad and Spirit—that are forcing legacy carriers to pay attention. Delta’s Dave Holtz also makes the list representing a large carrier that leads the industry in performance—and promises its corporate clients it will continue to do so. American’s Maya Leibman, meanwhile, makes the cut for showing the rest of the industry how mergers are done. BTN also named four innovative travel managers among 2015’s 25 Most Influential, as well as six technology pros, including Choice Hotels CEO Stephen Joyce; five leaders of suppliers that grew their businesses; four civil servants who have changed the business world; and one bank CEO who threw the world for a loop by reigning in his company’s card business to its North American home.
