In 2026, Southwest’s famous $59 one-way fares are primarily found on short-haul "shuttle" routes and intra-state connections during "Wanna Get Away" sales. Common 2026 destinations for these low fares include routes like Phoenix (PHX) to San Francisco (SFO), Las Vegas (LAS) to San Diego (SAN), and Oakland (OAK) to Burbank (BUR). You can also frequently find these deals on flights between major Texas hubs, such as Dallas (Love Field) to Houston (Hobby). These fares are usually available for mid-week travel (Tuesdays and Wednesdays) and require booking at least 21 days in advance. While $59 is the "headline" price, these tickets still include Southwest’s high-value signature perks: two free checked bags and no change fees. However, for 2026 holiday periods or long-haul cross-country flights, you should expect "base" sale prices to start closer to $99 or $129, as the $59 tier is increasingly reserved for regional "commuter" distances.
