Whose hubs where? How do I find out?
 

Can anyone tell me how I can determine which airlines have hubs in which cities? Ordered by city would be preferable, but any "list" would do.

Thanks in advance.

Here's one that's pretty out of date:

Dudster: You're right, that one's pretty out of date.

I think we could compile a US hub list on our own here amonst us Flyertalkers...

ATL: DL
BWI: WN
BOS: AA (secondary hub); US (secondary hub)
CLT: US
ORD: AA, UA
CVG: DL
CLE: CO
CMH: HP
DFW: AA, DL (secondary)
DEN: UA
DTW: NW
IAH: CO
MCI: YX
LAS: HP, National
LAX: (secondary for many: AA, UA, DL)
MEM: NW
MIA: AA
MKE: YX
MSP: NW
BNA: WN
JFK: (secondary for many: TW, DL, AA, etc)
EWR: CO
OMA: YX
MCO: DL
PHL: US
PHX: HP
PIT: US
PDX: DL
RDU: Midway
STL: TW
SLC: DL
SFO: UA
SJC: AA (reemerging)
SJU: AA
SEA: AS, UA
IAD: UA

presumably I've missed a few and am off on a few...but it's a start.

That's a pretty complete list. Here a just a couple of others I can think of.

DEN - Frontier
ATL - AirTran
MDW - ATA
MSP - Sun Country

LAS, PHX, HOU, MCI, and MDW - WN (I'm not really sure you'd call these hubs, but there are lots of connections at these airports)

A few more:

BWI: US secondary hub
DCA: US secondary hub
MCI: Vanguard (jet flights)
MCI: also US commuter hub
LAX: TW commuter connections

What about focus cities? I know of two:

LAX: TWA Focus City
PIT: AirTran Focus City
