This is a great deal for last minute travel if you are looking to head up to the Windy City in the next few weeks. Departures start as soon as Monday with travel available through November 3, 2018. Dates can be a bit tricky to find as this deal is selling out fast, but there are some still out there if you're diligent.
As an example below, I found seats departing IAH on Tuesday, October 23 and returning from ORD on Saturday, October 27, 2018. Travel days vary, but midweek departures are your best bet for finding this deal. One-ways can also be purchased for 45 dollars so you could piece together an itinerary involving one of those fares as well.
This airfare falls into United's Basic Economy category, meaning, all you can bring onboard is a small personal item, like a backpack or larger purse. If you find that too restrictive you can bump up to Standard Economy for $46 more roundtrip raising the total to $135, still a great deal on this route.
