Relaying some interesting statistics from Airliners.net over here:
This shows the difference in daily seats, flights, and seats per flight this year over last year. One caveat this year is the US + AA merger has helped to inflate the AA numbers, however US had a relatively small operation at ORD so much of this is indeed growth.
ORD/UA
Seats: 59300 (+4.6%)
Flights: 672 (+2.0%)
Seats per Flight: 88.2 (+2.6%)
ORD/AA
Seats: 47600 (+11.6%)
Flights: 519 (+2.8%)
Seats per Flight: 91.7 (+8.5%)
For comparison sake, here's the 10 largest hubs in the US:
Hub..........Seats.....YoY.....Flights.....YoY...Seat/Dep.....YoY
ATL/DL.....134000.....1.3%.....982.....-4.3%.....136.5.....5.8%
DFW/AA...95600.....5.7%.....827.....2.5%.....115.6.....3.1%
CLT/AA.....70400.....3.4%.....671.....2.4%.....104.9.....1.0%
ORD/UA.....59300.....4.6%.....672.....2.0%.....88.2.....2.6%
IAH/UA.......59200.....0.7%.....620.....0.3%.....95.4.....0.4%

------
A few things to take away:
- UA + AA at ORD is still smaller than DL at ATL.
- ORD is now larger than IAH in terms of both flights and passengers. (IAH held onto the passenger title last year)
- The increases in seats per flight show that the reductions in smaller regional jets is starting to go into full swing, thankfully.
- The reduction in smaller regional jets has not led to a reduction in flights, telling us that the flights are simply being flown on larger planes.
- If the upgauging (using larger planes) of flights continues to the point where average seats per flight amount to the equivalent of the AA operations at DFW and UA operation at EWR, then that alone will add 7 million annual passengers without a single flight being added.
