Air Wisconsin - AWI3930 - 2020/03/02

We are seeing some odd data on this flight that I need some help sorting out.

Flight: AirWisconsin - AWI3930 - March 2nd 2020
faFlightID: AWI3930-1582955170-airline-0137

We were able to successfully subscribe to this flight while it was taxing.

alert_id = 33760593

Shortly thereafter, the web link broke and the flight disappeared from Upcoming flights (/live/flight/AWI3930).

If the flight was canceled after it began taxing, we received no push notification. We now get this result from the FlightInfoEx endpoint

                "origin": "KORD",
                "destination": "KLIT",

                "destinationCity": "Little Rock, AR"
            }

What do -1 values for the times indicate?

Meanwhile the flight is tracking on other services:
