David G. Neeleman, JetBlue's founder and chief executive, said the program, which includes improved procedures for crew members and reservations, would be expensive, but it was more important for him to look at the long-term benefit of regaining customers' confidence in the company. In an interview on CNBC, he said Neeleman said JetBlue's first-quarter results would be hurt by the service disruptions. "Hopefully, it'll be something that's contained to the first quarter," Neeleman said. The company plans to file an 8-K outlining the impact and will provide new guidance for the quarter.
