Saturday I wrote about the high cost of summer airfares. I also included several tips for saving time and money this summer when flying. A couple of them were condensed due to lack of space, including this one: For flights out of MSP, sign up for Sun Country, IcelandAir, Delta and Sprit's e-mail or Twitter alerts.

Sun Country offers Wing It! fares on Tuesdays. Sign up here. Today's fares for the holiday weekend include the following:

These fares must be booked by 11:59 PM CT (Central Time) on July 1, 2014. (Fares are priced one-way.)
