JetBlue's corporate headquarters are in Long Island City, NY, not Aurora, CO, but they do have operations and customer service points at Denver International Airport (DEN) in the East Terminal for flights, with ticket counters open before departures and baggage service numbers for assistance, though no "office" in Aurora itself. If you're looking for corporate info, it's at 27-01 Queens Plaza North, Long Island City, NY; for airport help in Denver (near Aurora), check JetBlue's DEN airport page.
