Hey Jim,Problems 1-4 would be at least mostly cured by depeaking the hub operation. Doing some overflying of PHL should be a no-brainer.
Jim
You seem to be very professional and expierenced. I have noticed on Flightaware that in Philly USAirways sure has a lot of ground holds, on the other end of the spectrum my employer UPS seem to have ther acft off the ground in less than 15 minutes normally. Now I am talking at peak times with our widebodies heading overseas. Do you know the reason for this? Airport layout, Cargo prefererance?
Thanks
