When I last checked, it was something like 4 E70's, a 757, and a 319 for ORD service... So yes, we sometimes have them, but not often.

DFW-IAD is always E70, DFW-LAX CR7, and DFW-SFO 319.

DEN and ORD get the mix of Express and 757/319/320. Skywest CR7's generally to DEN and Shuttle America E70's to ORD.
