Yes, you can watch Netflix on a Southwest flight, but there is a major catch: you must download your shows and movies to your device before you board. While Southwest offers complimentary in-flight entertainment (including live TV and on-demand movies) that you can access via their "SouthwestWiFi.com" portal, their onboard Wi-Fi service does not typically support high-bandwidth video streaming through apps like Netflix, Hulu, or YouTube. The satellite Wi-Fi provided on most planes is designed for browsing the web, checking emails, and messaging; attempting to stream a full-length movie will often result in a "low bandwidth" error or constant buffering, which can be frustrating for you and slow down the connection for everyone else. In 2026, most modern Southwest aircraft have been upgraded with faster Wi-Fi, but the airline still officially advises guests to use the "Download" feature on the Netflix app to save content to their phone, tablet, or laptop. This ensures that you have a smooth, uninterrupted viewing experience regardless of the strength of the aircraft's internet connection, and it also allows you to enjoy your favorite shows without having to pay the daily Wi-Fi fee (currently $8 per device).
