If there's a route in the US system operated by Colgan that hasn't suffered a cancellation this year, I'd be surprised. It's showing 72% ontime for the Colgan route operated between CHO and LGA, which might be accurate given a loose interpretation of "on time." It's also showing a 0% cancellation rate, which I know to be false since I was forced to fly standby CHO-CLT-EWR during the measurement period when one of the Colgan flights was cancelled due to mechanical difficulties. My experience over the last 5-6 years has been that Colgan regularly cancels flights on B1900s and Saab 340s, and not infrequently on the CHO-LGA route.
It also states that Flt 4848 has an ontime rate of 47%???? That's odd since last night's 3hr 10min delay ought to be just a bit above average for this route, not 3x the average given by Flightstats.
