In 2026, you can watch Netflix on a Southwest Airlines flight, but not via the airline's "Live TV" portal; you must use your own device and have an active Netflix subscription. Southwest provides a "portal" that offers free live TV (like Bravo and CNBC) and a selection of movies, but it does not host the Netflix app directly. To watch your favorite Netflix shows, you should ideally download them for offline viewing on the Netflix app before you board, as this is the most reliable method. While Southwest has significantly upgraded its onboard Wi-Fi in 2026 to support streaming-capable speeds, the bandwidth can still fluctuate when 100+ passengers are all trying to stream simultaneously. Using the "Southwest Wi-Fi" (currently $8 for the day) will allow you to access the Netflix servers in real-time, but for the smoothest 2026 experience, "Downloaded" content is still the gold standard to avoid buffering during your flight across the country.
