Southwest Rapid Rewards members now have the chance to take free flights to Hawaii because of Southwest’s expanded partnership with ATA Airlines. As part of the expanded relationship, Southwest customers will be able to book flights on ATA through Southwest’s Web site, and burn credits for travel with ATA.

One of those destinations is Hawaii.

Free flights to the islands will be a bit “pricier” than the typical domestic U.S. awards, though — twice as many credits will be required.

Flights to Hawaii are slated to be available sometime between July and September.
