What does it mean for a flight to be "available for purchase" on Southwest?

When a flight is described as "available for purchase" on Southwest, it indicates that the flight remains open for booking, and there are seats available for travelers to buy. This means customers can select this flight as an option when searching for travel dates, and they have the opportunity to complete the reservation process.

In this context, the other options clearly depict scenarios where the flight cannot be purchased. A fully booked flight suggests that no more tickets can be sold, while a canceled flight indicates that it is not operating at all. Additionally, a flight that has limited seating requiring a waiting list implies that potential customers are not guaranteed a seat at the time of inquiry. Only when a flight is open for booking with available seats can a customer confidently add it to their itinerary and finalize the purchase.
