Still working on the ART segments, but let's try these for the rest.
MSP-ORD, UA, 727 (since the 727 is now available under the ground rules)
SYR-XXX, AA 707 (that's all that's left for AA!)
SYR-XXX and XXX-MSP, AA and NW, 707 (presumably) and D10 -- I'm thinking the only logical airport left for XXX is DTW (but I do have a less-logical one in mind if this is wrong)
