Washington, D.C. to Chicago
$117$27658% off
Round trip
Fly BWI to Chicago for just $117 round trip on Frontier, down from the usual $299, a 61% discount and one of the steepest cuts we've seen on this route. It's a nonstop hop that works well for a fall food-and-museums weekend, with deep-dish pizza and lakefront views on the other end. Fares on this route rarely dip this low, making it worth a look while it lasts.
