[02/21/2018 @ 10:37 AM] Old post clean-up. Fare gone. Removing from deal list.
Southwest has round-trip flights from Dallas (DAL) to Chicago (MDW), Detroit (DTW), or Pittsburgh (PIT) starting at $82 NONSTOP. $41 each-way. Flights January to early-March. Origin/Destination reversible. Very few Sunday returns. No Holidays.
Note: You can save an additional $125 if you purchase your Flight+Hotel together as a package on Southwest Vacations and apply the SAVE125 coupon code. Package coupon expires today, but the airfare deal should still be around.
