Works fine with Jetblue Blue.
Sorry to hijack this thread, but I made a third party booking with a Blue fare, and JetBlue won't let me cancel without paying a $50 fee to take over the reservation and also won't let me refund it to TravelBank, only lets me keep it as an open ticket.
How did you cancel it? I chatted with them several times already.
ETA: One of them now worked online. Yesterday none of them worked online, apparently it was a bug. As an aside, many of their reps have become super unhelpful recently.
