Round trip
Frontier has a nonstop BWI to ORD fare at $63, nearly 80% off the usual $309 round trip and right at the cheapest price we have ever tracked on this route. Chicago's deep dish, architecture tours, and lakefront are an easy weekend away at this price. This is about as good as domestic nonstop fares get this fall.
