Right!!
There are so many variables involved in on-time performance that such a list is meaningless.
You could sit on a taxiway at a departure airport with gorgeous weather bound for a destination that's cool but dry, having plenty of runways and ATC that knows how to keep things moving and still experiece substantial delays.
Been there, done that, due to weather conditions elsewhere that made issuing our clearance a low priority.
Instead of some list, the sensible traveler needs to try to be aware of those airports most subject to weather delays and consequent late day cancellations in any given season as well as rebook opportunities available at any given station.
Savy travelers already know this and don't rely upon some list of dubious value to guide them in their selections of airports and airlines.
I'd rather be trying to get to my destination from ATL in a delay and cancellation situation than from MSP, for example.
Lots more flights, better weather and plenty of concrete available for operations, although not on the list.
