Working on maximizing segments for a trip OAK-STL in November, I discovered pricing on UA's web site was the same for a number connecting cities doing OAK-DEN-XXX-ORD-STL and STL-ORD-XXX-DEN-OAK. What cities have I missed in the following list that have UA (preferred) or UAX flights both to/from ORD and DEN:

MSP
OMA
LNK
Madison WI
MKE
CID
DSM
Moline
PIA
MCI
SGF
OKC
MSY
DFW
COS
ICT
SLC
PHX

Thanks.
