Seen below, we found seats on Delta departing ORD on Saturday, September 15, and returning from SEA on Tuesday, September 18, 2018. Flights are mostly available on Monday through Thursday and Saturdays, but they are selling out quick so you'll have to play around to see if your particular dates work at this price point.
