If we fly from Chicago to Spokane, we would first go to MSP, either in a MD-90, from ORD, or an Embraer 175, from MDW. We'll be staying near the McCormick Center (conference). Offhand I'd opt for MDW for ease of access, even in the morning (against rush hour traffic), but the Embraer is a smaller plane (1-2 seating in FC), and is on Compass Air, dba Delta Connection. MD-90 is, of course, a bit larger (2-2 seating), but I think it's an older plane. Just a 90-minute flight, but which plane would you choose? If the MD-90, enough to justify the trip to O'Hare?

Not sure if I've ever flown Delta Connection.
