Every month FlightView reports on the on-time performance of airlines around the world based on the real-time flight information we collect. As well, the US Department of Transportation issues on-time performance of the major US airlines every month.
When we compare FlightView’s and USDOT’s views of airline performance, what do we see? Do our numbers match up? Are there any biases? Are the same airlines on top / bottom of our lists? Is one report better than the other?
