Delta.com vs Flightaware - Accuracy?
Flew in to MSP today on 2319 to catch 2477 to LAX/OGG. 2319 was running late and didn't get to the gate until 2:01p (21 min late). At 1:55p Delta.com showed 2477 leaving on time at 2:25p while Flightaware showed a 2:41p departure (16 min late). Fortunately Flightaware was correct. As I sat on the plane at 2:35p, awaiting door closing, delta.com still showed an on-time departure.
Does flightaware get their data from a more accurate source (within DL? FAA? Airport?) than delta.com? Is one generally more reliable than the other? |
IIRC Flightaware uses filed "wheels up" time from the flight plan

Why do the departure and arrival times on a scheduled airline differ from the information on the airline's web site? Airlines generally display the times that the aircraft departs and arrives from a gate. FlightAware presents the time that the aircraft departed and arrived, also known as the "wheels up" and "wheels down" times. At large airports or in various circumstances, there can be a significant difference in these times due to delays on the ground. Why do I care about wheels up / wheels down time for airline flights? Shouldn't I just track an airline flight on their web site? Maybe so; that's a good point. FlightAware's data may or may not be the most relevant for airline customers depending on the situation. One interesting aspect of FlightAware's tracking data for airlines is that although it doesn't offer gate arrival or departure times, if an airline is claiming (for example) that flight #482 will arrive at gate E6 at IAH at 4:18pm but FlightAware says the flight isn't going to touch down at IAH until 4:32pm, you might expect a delayed arrival at the gate or, less likely, a revised ETA from FlightAware. |
