Southwest Airlines is adding one of its longest mainland U.S. sectors for the 2026 holiday season, filing seasonal nonstop Fort Lauderdale–San Diego flights from November 21 on Boeing 737 MAX 8 aircraft. The roughly 2,269-mile city pair links a major South Florida station with Southwest’s largest California operation without requiring an overnight red-eye.
Published schedules list westbound WN2843 leaving Fort Lauderdale at 10:50 a.m. and arriving San Diego at 1:25 p.m. local time, with a block near five and a half to six and a half hours depending on the source’s rounding. Eastbound WN3056 is timed to leave San Diego at 9:25 a.m. and reach Fort Lauderdale at 5:10 p.m. Because the SAN departure leaves before the westbound flight arrives, the first day’s pair cannot be a simple out-and-back on one aircraft.
Southwest is not selling a uniform daily pattern for the entire winter. Coverage of the November–December schedule extension describes multiple network shapes that concentrate flying on the strongest holiday peaks, including the Saturday before Thanksgiving. FlyMag noted Southwest expects more than 4,600 system departures on Sunday, November 29, one of the busiest Thanksgiving return days. On dates without the through flight, connecting itineraries between the airports remain available. InsideFlyer described the operation as five times weekly on the MAX 8; FlyMag emphasized selected peak dates rather than a conventional every-day winter bank.
Competition will be immediate. JetBlue is scheduled to begin daily Fort Lauderdale–San Diego service on November 19 with Airbus A321 aircraft that can include Mint cabins. Alaska Airlines resumes seasonal daily flying on the same corridor around November 21 with 737s. That puts three carriers into a long Florida–California lane that has not always supported year-round nonstop competition from all three at once.
Southwest configures its 737 MAX 8 and 737-800 fleets with 175 seats in a single cabin after the airline’s move to assigned seating in January 2026. Extra-legroom rows offer about 34 inches of pitch, with preferred and standard seats around 31–32 inches and seat width near 17.8 inches on typical positions. On a westbound sector approaching six hours, that product differentiation matters more than on Southwest’s traditional short-haul flying. Boeing lists MAX 8 range well beyond this domestic stage, helped by CFM LEAP-1B engines and aerodynamic changes versus the classic 737-800.
Southwest has also been retrofitting aircraft with new Recaro seats, larger overhead bins, and in-seat power; a mid-2026 regulatory filing cited by trade coverage said more than 100 aircraft had already received refreshed seats. That cabin work is especially relevant on a coast-to-coast daytime flight sold without a premium cabin, where assigned seats and extra-legroom rows are the main upsell levers.
For Fort Lauderdale, the route extends a network already heavy with medium-haul flying; for San Diego, it adds a daytime coast-to-coast option from a carrier that ranks outside the top few by local departures. Fares and exact November–December dates should be checked on Southwest’s booking tools, since the holiday template can change by day. Aircraft type, launch date, flight numbers, and competitive overlap are drawn from FlyMag and InsideFlyer reporting dated September 17–18, 2026.
