Sample flights

Because Southwest does not generally specify its sale routes, you can either search for your desired route or check the Low Fare Calendar to see which routes are available.

If you use the carrier's search engine, you'll know the promo code was applied when you see a green banner at the top indicating such, along with the green price tag.

if you use the Low Fare Calendar, sale fares will appear under the crossed-out original price.

Based on a test search conducted for this story, you could book a round-trip ticket from Chicago's Midway International Airport (MDW) to Kahului Airport (OGG) in early May for $425.

This sale includes Wanna Get Away and Wanna Get Away Plus fares, which allow travelers two free checked bags, one free carry-on and one personal item. These tiers also include free inflight entertainment and messaging.

You can change or cancel flights up to 10 minutes before departure. However, if you cancel a Wanna Get Away trip, you will receive a flight credit in lieu of a refund.
