I booked B6 615 JFK-SFO several months ago. Today I received an email stating that I was now on B6 515, two hours later.

JetBlue is telling me this is a schedule change, not a cancellation. Since it it less than three hours' difference, I am not entitled to free rebooking.

Flight 615 no longer exists on my day of travel. Flight 515 has always existed.

How can an airline remove a flight from the schedule, move passengers to a different pre-existing flight, and claim that there was no cancellation?. An hour on the phone and escalation to a supervisor didn't get me anywhere. According to JetBlue, removal of a flight from the schedule is not a cancellation, if the passenger is rebooked. Nothing would ever be a cancellation under this reasoning.

When I asked where I could find what JetBlue considers to be a cancellation, I was only directed to the Contract of Carriage (which does not define a cancellation), and "the website."

And is it worthwhile to file a DOT complaint about this?
