To change your JetBlue flight time by phone, find your confirmation code and last name, then call JetBlue Customer Service at 1-866-JETBLUE (1-866-738-0706), and be prepared for a potential $25 fee plus any fare difference, though self-serving online at jetblue.com is often free and faster for simple changes. Agents can assist with updating flights, but expect charges for changes made over the phone unless it's a significant schedule change by JetBlue (over 3 hours). Jauntlet.comhttps://jauntlet.com/
