It’s per leg. It’s not a good deal/benefit. Most often it’s more expensive then buying a confirmed seat. To use our 50% off confirmed tickets for wife and kids you also have to buy a confirmed ticket and travel with them. Once again not a good benefit. We used to be able to give our friends a confirmed ticket for 25% off. That is now gone. Once again a good benefit that was taken away. Travel benefits are way behind the industry norm.
