This is no longer a live booking comparison. Spirit Airlines announced an orderly wind-down and ended operations on May 2, 2026. Southwest continues to operate; Spirit itineraries are not a current alternative. The remaining rows preserve the final status and historical distinction without implying that Spirit flights can still be purchased.
Southwest's filed year-end 2025 fleet was 803 Boeing 737s. Spirit formerly operated A320-family aircraft, but its May 2026 wind-down superseded the earlier restructuring fleet plan and every older FlightQ fleet count.
Spirit's former unbundled products are historical and should not be used for a current purchase decision. Southwest's current assigned-seating and baggage terms should be checked directly on Southwest because fare benefits can change.
There is no current Southwest-versus-Spirit route choice after Spirit's shutdown. Travelers looking for a low-fare alternative should compare the operating carriers serving the specific origin and destination.
Spirit is not operating, so Southwest is the only current airline in this historical pairing. Use a live route search to identify other operating alternatives.
