JetBlue doesn't have a physical, staffed "Hamilton Office" in the traditional sense but serves the Hamilton, Ontario area (near John C. Munro Airport) through its central reservations and online services, offering flight bookings, changes, and baggage info via phone (1-800-JETBLUE) or their website/app, with specific airport assistance at John C. Munro Hamilton International Airport (YHM) on flight days for their routes, often to destinations like Fort Lauderdale (FLL).
