Hey man not saying one is better than the other, just saw the facts and had to comment. I think they both do a good job being on time. Its just hard to use DOT on time stats to support an argument when you operate through hubs like EWR, ORD, ect. Speaking for EWR, every flight after 12pm is going to be delayed at least 30 mins automatically. Having a 75% + on time arrival rate even with that is pretty darn good I'd say. Obviously the other 25% is mainly all the EWR flights.
