Southwest Airlines is preparing to add a new long-haul domestic route between Florida and Southern California, with flights between Fort Lauderdale-Hollywood International Airport (FLL) and San Diego International Airport (SAN) scheduled to begin on November 21, 2026. The service will cover more than 2,500 miles and take roughly six hours, creating a new nonstop option between two major leisure and business markets.
The route is notable because Southwest will operate it with the Boeing 737 MAX 8, an all-economy aircraft that will spend a substantial portion of the day crossing the United States. According to Cirium schedule data, Southwest plans to operate the route five times per week, rather than daily, during its initial launch period.
For passengers traveling between South Florida and San Diego, the new service removes the need for a connection at another Southwest hub. It also adds another nonstop choice to a market that is already served by Alaska Airlines and JetBlue Airways, giving travelers three airlines to consider on the corridor.
Southwest FLL-SAN Route Begins November 21
Southwest’s westbound service will operate as WN2843, departing Fort Lauderdale at 10:50 AM local time and arriving in San Diego at 1:25 PM. The scheduled block time is approximately 6 hours and 35 minutes, reflecting the considerable distance and prevailing westbound operating conditions.
The return flight, WN3056, is scheduled to leave San Diego at 9:25 AM and reach Fort Lauderdale at 5:10 PM. Despite the longer geographic distance associated with a transcontinental journey, the eastbound schedule has a shorter planned block time of 5 hours and 45 minutes.
The daytime schedule is particularly relevant on a flight lasting around six hours. Unlike certain long transcontinental services that depart late in the evening and arrive the following morning, Southwest’s planned FLL-SAN operation does not require passengers to spend the night onboard. Travelers can therefore make the crossing during normal daytime hours without dealing with an overnight red-eye.
San Diego Is a Major Southwest Airport
San Diego is an important part of Southwest’s network, and the new Fort Lauderdale service fits into the carrier’s already extensive operation at San Diego International Airport. Cirium data for September 2026 places SAN tenth among Southwest airports by scheduled departures, with 3,573 departures, approximately 577,249 seats, and more than 485 million available seat miles scheduled during the month.
The breadth of Southwest’s San Diego network helps explain why the airline can support a route of this length. The carrier connects the Southern California airport with destinations across the United States, ranging from relatively short regional services to some of its longest domestic flights.
Southwest’s longest San Diego route is currently the 2,614-mile service to Daniel K. Inouye International Airport in Honolulu, operated twice daily. Its second-longest is the 2,588-mile connection to Boston Logan International Airport, which operates daily. The FLL route will therefore become another significant transcontinental link in the airline’s San Diego schedule.
At the shorter end of Southwest’s San Diego network are flights to destinations such as Santa Barbara, only 192 miles away. Meanwhile, San Jose has the highest frequency, with as many as 12 daily Southwest flights. The FLL service sits at the opposite end of that spectrum, emphasizing Southwest’s ability to use its 737 fleet across a wide range of distances.
Fort Lauderdale Adds Another Long-Distance Southwest Link
Fort Lauderdale is less significant to Southwest than San Diego in terms of overall scheduled activity, but it remains an important station in the carrier’s network. Cirium data shows 704 Southwest departures scheduled from FLL during September 2026.
Those services cover a broad range of distances. Southwest’s Fort Lauderdale network stretches from short flights of approximately 178 miles to Orlando to longer services reaching around 1,703 miles in Denver. Baltimore currently has the highest Southwest frequency from Fort Lauderdale, with as many as five flights per day.
The new San Diego route will stand out because of its length. At roughly 2,500-plus miles, it extends well beyond most of the carrier’s existing Fort Lauderdale flying and strengthens the airport’s connection to the western United States.
Alaska and JetBlue Already Serve the Market
Southwest will not enter the FLL-SAN market alone. Alaska Airlines already operates the route seasonally with Boeing 737 aircraft, while JetBlue Airways is also preparing to introduce its own service.
JetBlue’s flights are scheduled to begin on November 19, two days before Southwest’s launch, and will operate daily with a 159-seat Airbus A321. The airline will also offer its Mint business-class cabin on the route, providing a premium option on a journey where the total flying time can approach six hours.
Alaska’s seasonal FLL-SAN service is scheduled to restart on November 21 and will also operate daily. The airline’s previous operation recorded an 84.3% load factor in the 12 months through June, according to Cirium data, indicating substantial demand for the city pair.
With Southwest joining Alaska and JetBlue, the market will feature three different airline products and aircraft configurations. Southwest’s five-weekly 737 MAX 8 service will provide another nonstop choice, while JetBlue will emphasize its A321 and Mint offering and Alaska will continue its seasonal Boeing 737 operation.
A Six-Hour Route With Strong Leisure Appeal
The new Southwest route reflects the importance of nonstop domestic flying between major leisure destinations. South Florida and San Diego are both substantial tourism markets, while their geographic separation makes connecting itineraries considerably less attractive when a nonstop alternative is available.
For Southwest, the FLL-SAN service also demonstrates how its network can stretch the capabilities of the 737 MAX 8 beyond shorter domestic sectors. A six-hour scheduled flight is a demanding assignment for an all-economy narrowbody, but the daytime timetable avoids the additional inconvenience of an overnight operation.
When Southwest launches WN2843 and WN3056 in November, passengers will have a new way to cross the country without changing planes. With Alaska, JetBlue, and Southwest all scheduled to serve Fort Lauderdale-San Diego, the route is also set to become a particularly visible example of competition on one of the United States’ longer domestic city pairs.
