Madison needs Southwest. Here’s why:

Many of their fares are lower when
booked as a round trip, or a multi-leg, in advance. However, unlike almost all other airlines, all of their fares are either fully refundable, or you get a full credit. There is no penalty for canceling a “super dooper” low discount fare. As a result, most travelers on SW book round trips, and then do not use the return leg, or even a leg in the middle of the itinerary. However, irrespective of whether you turn up for any part of the trip, the first leg, or the last, your itinerary remains in place. When you’re done with your trip, your unused portions are either refunded automatically, or sit as a credit to be used whenever you want.
