looks like the 6a MCI-ORD is getting cancelled due to republic crew availability:
REPUBLIC AIRLINES AS AMERICAN EAGLE
MCI 600A 82
ORD 9 T3 H5 736A
1MCI/FX CANCEL MCI -ORD -CRX-CXLD DUE TO CREW AVAILABILITY*1317
7MCI/AUTO REACCOM CXL FLT COMPLETED SEE N*P1AA4225MCI03NOV *1338*CRCYMG
(given your layover times, i'm guessing that's what you were on.. even if not, you were easy to move over to a more direct route as they were doing reaccomodation..)
interesting that aa.com is still selling it! expertflyer flight status shows it "scheduled", but offers the above in the comments..
