Want to go to Chicago this summer? Or Washington, D.C. or Los Angeles or a handful of other cities? Don't book until you've checked the fares offered by Sun Country. For instance, you can get to Chicago for $84 one-way, a fare that nearly matches Amtrak rates. To get the "Sun Drop" rate, book by May 8 for flights May 12 through August 31. Travel is valid on Mondays, Tuesdays, Wednesdays, Thursdays and Saturdays; 14 day advance purchase required.

Destinations with discounted fares also include Lansing, Mich., Boston, Mass., New York City, Seattle, Wash., and San Francisco. May 26 is a blackout date; fares may sell out quickly.
