This is a repeat of the same thing that happened at LGA pre-9/11. You would think the government would learn that you can’t arbitrarily lift slot controls without providing some kind of mechanism to cap demand.
I haven’t seen a comprehensive document of flight additions by carrier at ORD over the past year. Other than Independence, I don’t know what carriers have actually added service. Please post if you know where those additions have come from other than UA and AA who we know have added flights.
I’m not sure that I agree with the FAA’s logic that delays at ORD should be eliminated because they create havoc throughout the system. Yes, ORD has delays but it is the marketplace that should decide how to isolate the ORD problem and not the government. Airlines have learned to isolate ATC and weather problems at problem hubs and the FAA needs to learn to do the same. If ORD is a delay problem and delays cause an unexpected increase in traffic to NYC because a storm finally moves away from ORD and traffic can now flow, NYC controllers need to limit the amount of traffic which can flow to NYC to what was originally scheduled. The converse is true if backups develop.
I too believe that AA made a major strategic mistake by so quickly dismantling STL given the capacity problems at ORD. Although AA does have plenty of capacity at DFW, there are some O&Ds that can’t be efficiently served going that far south. Likewise, UA may think twice about any plans to reduce DEN given that it is a workable but costly hub. DEN is within an RJs flight range of about 2/3 of the United States by geography and even more with the EMB 170. Shifting a great deal of connecting traffic to DEN would allow UA to preserve its high frequency services to the top domestic business cities while and its international services, both of which are well-supported by the local Chicago community. Flights to smaller cities which are primarily connecting in nature might well be moved to another hub.
