Travelzoo reported that a fare war has sprung up among major airlines for summer and fall travel out of MSP.

According to the site, the sale ends Monday, June 25. The lowest prices can be found on Tuesdays and Wednesdays, in most cases. The sales are for travel between July 10 to November 14.

Here are sample roundtrip airfares, but check other destinations too.

Chicago $98

Las Vegas $133

Denver $174

Washington D.C. $209

Boston: $281

Orlando $300

Los Angeles $325.

The airlines still like to keep us guessing. So much for the conventional wisdom that fare sales start midweek.
