Southwest did not launch any sale that started on 25 Dec 2025 or 31 Dec 2025—its big promotions happened earlier in the fall. However, travellers flying on Christmas Day or New Year’s Eve could take advantage of several new flights, routes and book‑ahead deals that were announced in 2025 and were available for travel on or after those dates.

| Red‑eye flights (launched Feb–Apr 2025) | Southwest introduced twenty overnight routes; these began between 13 Feb 2025 and 8 Apr 2025 and continued through the end of the year. The flights include east‑bound overnight services from Las Vegas to Atlanta, Baltimore (starting 13 Feb), Chicago, Nashville and Orlando (starting 6 Mar); Los Angeles to Baltimore (13 Feb), Chicago and Houston (6 Mar) and Nashville (13 Feb); Phoenix to Atlanta and Orlando (6 Mar) and to Baltimore (13 Feb); Denver to Baltimore (6 Mar); Sacramento and San Diego to Baltimore (6 Mar); and long‑haul red‑eyes from Honolulu, Kona and Maui to Las Vegas and Phoenix (8 Apr). By late December these flights offered overnight options for people travelling on the holiday dates. | The Points Guy article details the start dates for each red‑eye route. |
| Schedule‑extension routes (March–Oct 2025) | Earlier in 2025 Southwest extended its schedule and added several new routes that would still be operating by late December. On 6 Mar 2025 it launched new domestic routes such as Austin–Milwaukee (weekdays), Austin–Reno (weekends), Nashville–Indianapolis (Sun–Fri) and Sacramento–Tucson (weekends). International growth included Saturday‑only service from Nashville to Cabo San Lucas and Punta Cana and from Sacramento to Puerto Vallarta starting 8 Mar 2025. Later the airline announced daily service between San Diego and Fresno and an Austin–Jacksonville route beginning 2 Oct 2025. All of these flights were bookable and operating by December. | Southwest’s Feb 6 2025 press release lists new domestic and international routes starting in March, and The Points Guy confirms the Oct 2 start of San Diego–Fresno and Austin–Jacksonville. |
| Special/seasonal flights | Las Vegas-based “special flights” were added throughout 2025 for major sports events and the National Finals Rodeo. These included 59 extra flights for college football games, 54 for NFL games and additional flights for music festivals and December’s National Finals Rodeo, giving travellers more holiday travel options. | Las Vegas Review‑Journal article summarises the special flights. |
