Southwest Airlines is currently in the middle of a major fleet-wide upgrade to provide USB-A and USB-C power ports at every seat. In 2026, most of their 737 MAX 8 aircraft and a significant portion of their older 737-800 fleet have been retrofitted with these ports, located on the seatback in front of you. However, many of the older 737-700 planes still do not have in-seat power. Because Southwest is still in the "transformation" phase, it is a peer-to-peer "best practice" to check your specific aircraft type on the Southwest app before your flight or simply come prepared with a portable power bank. Southwest has accelerated its $1 billion investment in cabin upgrades, which also includes larger overhead bins and faster Wi-Fi. While you can't guarantee power on every single flight in early 2026, the odds are much higher than they were just two years ago, especially on longer "overnight" or transcontinental routes where staying charged is a priority for passengers.
