Brinker said the airline had never experienced a full meltdown before, so it hadn’t needed to use this type of database. “The system, which was developed in 24 hours and implemented in the middle of JetBue’s crisis, has now been implemented as a full-time system,” he said. “It’s real behind the-scenes improvement for both our crew members and customers,” he said. JetBlue is also improving the way it communicates with its customers, including pushing out automated flight alerts to customers via e-mail and mobile devices.
