JetBlue Plans For Disruptions But Expects Successful Res Switch

JetBlue is planning to shut down most functionality on its consumer and corporate online booking sites, as well as in global distribution systems, beginning Friday at 12 p.m. EST for at least 24 hours as it converts from the Navitaire reservation system to Sabre's. Despite the likely revenue hit--which jetBlue officials were reluctant to estimate--executives expressed confidence in their contingency planning as they spoke today with analysts about the company's fourth-quarter performance.
