Fly nonstop from Chicago-ORD to Las Vegas for $139 roundtrip on either American or United Airlines from late August through December. For those in Sin City who want to check out the Second City, this fare works in reverse.
As an example, on Delta, I found seats departing ORD on Saturday, November 9, and returning from LAS on Tuesday, November 12, 2019.
Fares are available at this price starting on select dates in late August with departures valid through early December, returns in late December possible.
You'll need to be flexible with your travel window to find dates that work, but your best bet is searching in September and early December. American's inventory is selling out quickly, so on most dates, you'll find these fares operated on United aircraft.
American fares include one small personal item and one standard piece of carry-on baggage. United includes only one small personal item – a standard sized carry-on is not allowed. Checked bag fees start at $30 each way.
Seats will be assigned at random upon check-in for this price.
Spirit Airlines is price matching at $135 roundtrip during September.
American's Economy Fare is a whopping $193 more roundtrip, which comes to $332. This will include one piece of checked luggage, which is the cheaper option than paying for luggage at the airport.
