|Quoting B4real (Reply 4):|
-AA (DFW, MIA, ORD) - All big, but not quite so even
-UA (ORD, IAD, LAX, DEN, SFO) - Not quite so even.
-DL (ATL, CVG, SLC, JFK) - Very ATL heavy. JFK may soon close in on being very equal to SLC and then CVG.
-US (PHL, PHX, LAS) - Can't quite tell b/c of US/HP blend.

AA: DFW is about 50% larger than ORD
UA: ORD is about 65% larger than DEN
DL: ATL is twice as big as any of their other hubs
US: CLT is actually US' largest hub, about 25% larger than their second-largest, PHL, PHX third, and it wouldn't surprise me to find that DCA was larger than LAS (in terms of flights, LGA is larger than both, but aircraft-capacity-wise, that is not the case)
CO (left off your list): IAH is about 75% larger than EWR
