B6 operates its primary operations out of heavy-use (and some slot-restricted) airports, such as JFK and LGA. But I'm surprised about F9 in particular, especially with respect to NK, given that their fleet is of similar planes (A319/A320/A321), and that both primarily outsource their ramp and gate services (except for NK, at FLL).
Again, AC, B6, and F9 have a disproportionate amount of their operations out of cities with snow and ice, so their planes will often have delays on snow days, and even will have delays on non-snow winter days when they have to de-ice. NK has a disproportionate amount of their operations out of non-snow cities, so they will not be faced with those delays. I bet if snow/de-icing delays were eliminated from these on-time performance calculations, AC, B6 and F9 will move way up on the list and NK way down.
