IAH - PHL has definitely been reduced (thanks Jeff). I have had more then one itinerary changed due to these cuts. PHL is beuing very downsized for UA. In addition to IAH, Jeff has reduced ORD (mainly Express, and US has more flights), DEN, EWR. IAD continues to be a non entity, just a few express flights, generally late. LAX was dropped until Virgin America came in, now UA has an early morning flight.
Jeff does not like PHL
PHL is going out of the network. Good for those switching to the new AA here.
