Do these on-time stats factor de-icing times? It would be a massive red flag for the reliability of these stats if they did not equally factor this in across the board. Isn't it obvious that having to deice is going to take longer than not having to?
United Airlines have a 73% OTP at Newark Airport, which is one of the most congested in the US, and is also a cold-weather airport. Ditto for DL at JFK and LGA, who manage a 76% OTP at both airports.
I mean come on, in Chicago, which has some of the worst winter weather in the US, UA manages an 86% OTP. 51% is absolutely, laughably, hilariously bad.
