Spirit Airlines' $100 sale means flying nonstop from MSP to 13 cities for $24 to $50 each way. I've listed the cities below and the valid dates. There is a catch: You have to join its Fare Club for $60, which will automatically renew for $70 after a year. Details here.

Keep in mind that Spirit is the airline that charges for everything, including bags placed in the overhead, snacks and boarding passes. Read Spirit 101 to find out about the fees.

If you book one of these cheap fares today, save $12 if use the code 12OFFPK (all caps, no spaces) in the promotion code box. Another way to save is to buy your ticket at the airport (MSP Terminal 1--Spirit moved out of Terminal 2 at the beginning of the year). You will save $17.99 per leg in utility fees during the sale or at any other time you purchase Spirit tix at the airport. I have not personally tried this myself, but the PR person confirmed it.

I recommend taking earlier flights on Spirit when possible. Its on time performance has been dismal in the past. Your chances of getting out on time are better on any airline if you take the first or second flight of the day. Take the last flight of the day and you're playing the odds. You can check your flight's on time performance at www.flightstats.com. An average on-time performance is 80%. If you see numbers around 50% or less, you'd better be a patient person not traveling with small children.
