I don't have Pinnacle's on time performance but I can say that I use them to commute to and from DTW almost every week and I can honestly say that their on time performance on the flights I have been on is terrible. I would say that less than 20% arrive within 15 minutes and less than 1% arrive at or prior to scheduled arrival. Then once you are at the gate it takes another 5-15 minutes just to get parked!
