JetBlue CEO first witness in US lawsuit against 2 airlines Government lawyers used airline executives’ own words in trying Tuesday to persuade a federal judge to kill a partnership between American Airlines and JetBlue Airways. The government argued that the deal is, in effect, a merger that will cost consumers $700 million a year in higher fares. It said JetBlue’s pending purchase of Spirit Airlines will make matters even worse for travelers. JetBlue CEO Robin Hayes was the first witness in the trial in federal district court in Boston over the federal government’s antitrust lawsuit against American and JetBlue. The airlines are coordinating schedules and sharing revenue from flights in the Northeast, including New York-area airports. Hayes was quizzed about his own previous statements criticizing joint ventures involving other airlines and a 2019 comment that the airline industry “has never been more concentrated than it is today,” which he said led to higher fares and poor service. Hayes testified that regulators had not imposed enough limits on those deals.
